wcalc(1)

📦 version 2.5, in debian bookworm, debian trixie, nixos 26.05, nixpkgs unstable, ubuntu jammy, ubuntu noble, ubuntu questing, ubuntu resolute, ubuntu stonking

okay bestie, welcome to wcalc(1) — yes that's the General Commands Manual page, and yes we're about to make a calculator sound like the most fun thing that's ever happened to your terminal 💅

💖 NAME 💖

wcalc — a natural-expression command-line calculator 🧮✨

🎀 SYNOPSIS 🎀

wcalc [ options ] [ expression ... ]

🦋 DESCRIPTION 🦋

okay so wcalc is a command-line calculator and the whole point of it is that it accepts all valid mathematical expressions. Like, all of them. It's giving main character energy for math 🫶

Here's what it's got:

  • all standard mathematical operations
  • parenthesis
  • brackets
  • trigonometric functions
  • hyperbolic trig functions
  • logs
  • boolean operators

Now the fun part — the way it takes input, because there's a whole vibe check happening here. wcalc accepts input in a variety of manners:

  1. If no mathematical expression is given at the commandline, it will evaluate the contents of an environment variable named wcalc_input if one exists.
  2. If that variable is not set, wcalc will try to read input from standard input (i.e. piped input).
  3. If there is no input from that, wcalc enters "interactive" mode. Interactive mode has more features. 👑

While in interactive mode, detailed information about commands, functions, symbols, and variables can be obtained by executing:

\explain thing-to-explain

no cap, that's the whole cheat code. 🧚

✨ OPTIONS ✨

  • -H or --help — Prints a help usage message to standard output, then exits. 📖
  • -E — Specifies that numerical output should be in scientific notation. 🔬
  • -EE — Specifies that numerical output should NOT be in scientific notation. 🙅
  • -PXXX — Sets the "precision", or the number of decimal places displayed, to be XXX. This setting only affects output, not internal representations. If the precision is set to -1, the number of decimal places displayed will depend on the value. Precision is set to autoadjust (-1) by default. Example: wcalc -P6 💅
  • -v or --version — Prints the version number and exits.
  • -d or -dec or --decimal — Results are printed in decimal (base 10). This option is the default, and does not have a default prefix to indicate that numbers are in base 10. 🔟
  • -h or -hex or --hexadecimal — Results are printed in hexadecimal (base 16). Numbers printed in hexadecimal have a prefix of 0x unless the -p or --prefixes option is used. 🌈
  • -o or -oct or --octal — Results are printed in octal (base 8). Numbers printed in octal have a prefix of 0 unless the -p or --prefixes option is used.
  • -b or -bin or --binary — Results are printed in binary (base 2). Numbers printed in binary have a prefix of 0b unless the -p or --prefixes option is used. 🤖
  • -p or --prefixes — Toggles printing prefixes for hexadecimal, octal, and binary forms.
  • -l or --lenient — Makes the parser assume that uninitialized variables have a value of zero. 😌
  • -r or --radians — Toggles whether trigonometric functions assume input (and output) is in radians. By default, trigonometric functions assume input is in degrees. 📐
  • -q or --quiet — Toggles whether the equals sign will be printed before the results. 🤫
  • -c or --conservative — Toggles accuracy guards. okay this one needs the full lore, so here it is: Because of the way floating point numbers are stored in computers, some numbers cannot be represented exactly (such as 0.1). Because of this, calculating with those numbers can produce results that are not exactly correct, but are different from the correct answer by a very small value (smaller than the floating point value can represent accurately). For example, the calculation of 1-.9-.1 can return an extremely small number that is not zero but is less than what can be represented accurately, and thus for all intents and purposes, it is 0. The accuracy guard feature will round numbers to zero if they are less than the representable accuracy of the floating point number. However, sometimes numbers that small or smaller need to be displayed, and thus the accuracy guard should be turned off. Alternatively, the number of internal bits could be increased, which makes it possible to represent numbers with more accuracy. 💀
  • -u or --units [type] — Prints units used for conversions; parameter type can be: lengths, areas, volumes, masses, speeds, powers, forces, accelerations, temperatures, angles, or pressures. If the parameter is not supplied, all units are printed. 📏
  • --remember — Toggles whether or not expressions that produce errors are remembered in the history. Does not affect command-line math. 🧠
  • **--round= { none | simple | sig_fig } — Wcalc can attempt to warn you when numbers have been rounded in the output display. It has two methods of keeping track---either by using significant figures (sig_fig), or by a simple digit-counting algorithm. Rounding in the command-line version is denoted by a tilde before the equals sign (~=). Rounding in the GUI version is denoted by changing the text color to red. In some cases, Wcalc may think that the number has been rounded even if it shouldn't have been necessary (this is because of the way floating point numbers are represented internally). 🚨
  • --dsep=X — Sets the decimal separator character to be X.
  • --tsep=X — Sets the thousands separator character to be X.
  • --idsep=X — Sets the input-only decimal separator character to be X.
  • --itsep=X — Sets the input-only thousands separator character to be X.
  • --bitsXXXX — Sets the number of bits of memory that will be used to internally represent numbers to be XXXX. The default is 1024. Set higher if you need to work with extremely large or extremely small numbers, set lower if you want to use less memory. 🧮
  • --ints — Toggles whether long integers will be abbreviated or not. This conflicts with engineering notation for large numbers, but not for decimals.
  • --verbose — Toggles verbose mode, which displays the expression to be calculated before calculating it. 🗣️
  • --defaults — Prevents reading the .wcalcrc file.
  • -C or --color — Toggles the use of color in the commandline output. 🌈 (yes, the tool is also a little bit extra, we love that for it)

🍓 USER-DEFINED VARIABLES 🍓

Variables are supported and may be assigned using the = operator. To assign a variable use the form:

foo = anylegalexpression

Thereafter, that variable name is the same as the literal value it represents. Expressions can be stored in variables like this:

foo = 'anylegalexpression'

Expressions stored this way will be interpreted at evaluation time, rather than assignment-time. Note that these cannot be recursive. 🙈

All variables may also be stored with a description of what they are. This description is added in the form of a quoted string after the assignment, like this:

foo = 'anylegalexpression' 'description'

👑 ACTIVE VARIABLES 👑

Active variables are designed to give a functionality similar to user-defined functions. They are variables that rather than representing a value, represent an expression that is evaluated whenever the variable is evaluated. This expression may contain other variable names. For example, after the following sequence of commands:

foo=5
bar='foo+4'

The variable bar will evaluate to 9, or four more than whatever foo evaluates to be. These can be stacked, like so:

baz='sin(bar)+foo'

In this case, baz will evaluate to be 5.15643, or the sin of whatever foo+4 is plus whatever foo is. 🤯

To demonstrate the utility of these active variables, here are two functions written by Stephen M. Lawson. The first computes the weekday of a given day (dy) in a given month (mo) in a given year (yr). The value it returns is in the range of 1 to 7, where 1 is Sunday, 2 is Monday, 3 is Tuesday, and so forth. 📅

weekday='(((floor((yr - floor(0.6 + 1 / mo)) / 400) - floor((yr -
floor(0.6 + 1 / mo)) / 100) + floor((5 * (yr - floor(0.6 + 1 / mo))) /
4) + floor(13 * (mo + 12 * floor(0.6 + 1 / mo) + 1) / 5)) - (7 *
floor((floor((yr - floor(0.6 + 1 / mo)) / 400) - floor((yr - floor(0.6 +
1 / mo)) / 100) + floor((5 * (yr - floor(0.6 + 1 / mo))) / 4) + floor(13
* (mo + 12 * floor(0.6 + 1 / mo) + 1) / 5)) / 7)) + 1) + 5 + dy) % 7 +
1'

The second function computes what day Easter will be for a given year (yr) and returns an offset from March 31st. For example, for the year 2005, it returns -4, which means March 27th. Because of leap-year problems, this only works from the year 1900 to 2099, but is a good demonstration nevertheless. 🐣

easter='((19 * (yr - 19 * floor(yr / 19)) + 24) - floor((19 * (yr - 19 *
floor(yr / 19)) + 24) / 30) * 30) + ((2 * (yr - 4 * floor(yr / 4)) + 4 *
(yr - 7 * floor(yr / 7)) + 6 * ((19 * (yr - 19 * floor(yr / 19)) + 24) -
floor((19 * (yr - 19 * floor(yr / 19)) + 24) / 30) * 30) + 5) - floor((2
* (yr - 4 * floor(yr / 4)) + 4 * (yr - 7 * floor(yr / 7)) + 6 * ((19 *
(yr - 19 * floor(yr / 19)) + 24) - floor((19 * (yr - 19 * floor(yr /
19)) + 24) / 30) * 30) + 5) / 7) * 7) - 9'

and that's just part one bestie, there's more coming so don't go anywhere 💖

✨ BUILT-IN SYMBOLS ✨

okay so wcalc comes preloaded with goodies, and there's two flavors of them: functions and constants. that's it, that's the whole vibe. let's get into it 💅

🌸 FUNCTIONS 🌸

bestie, the functions in wcalc are almost all self-explanatory (the manpage said it, not me 😌). here's the rundown anyway:

  • sin cos tan cot — the standard trigonometric functions, iconic behavior fr
  • asin acos atan acot or arcsin arccos arctan arccot or sin^-1 cos^-1 tan^-1 cot^-1 — the standard arc-trigonometric functions. three whole ways to write them, pick your fighter 🎀
  • sinh cosh tanh coth — the standard hyperbolic trigonometric functions
  • asinh acosh atanh acoth or arcsinh arccosh arctanh arccoth or sinh^-1 cosh^-1 tanh^-1 coth^-1 — the standard arc-hyperbolic trigonometric functions
  • log ln logtwo — log-base-ten, log-base-e and log-base-two, respectively. and remember, you can also construct log-base-X of number Y by computing log(Y)/log(X) ✨
  • round — returns the integral value nearest to the argument according to the typical rounding rules
  • abs — returns the absolute value of the argument
  • ceil ceiling floor — returns the ceiling or floor of the argument

  • fact — returns the factorial of a number
  • Gamma — returns the value of the Gamma function at that value
  • lnGamma — returns the value of the log Gamma function at that value
  • zeta — returns the value of the Riemann zeta function at that value
  • sinc — returns the sinc function (for sinus cardinalis) of the input, also known as the interpolation function, filtering function or the first spherical Bessel function, is the product of a sine function and a monotonically decreasing function 🌊

🔮 CONSTANTS 🔮

wcalc supports a LOT of constants. some are special (hi pi 👋), and some are just mathematical or physical constants that have been hardcoded in. the physics constants are taken from http://physics.nist.gov/constants, and should all be in predictable SI units 💖

the value of pi is special, because it is calculated to however many bits of precision have been specified with the \bits command. the default number of bits is 1024, or a value of:

💀 SPECIAL SYMBOLS 💀

there are some special symbols that wcalc accepts as input for compound operations. lowkey iconic of it:

  • @Inf@ — Symbol that represents Infinity
  • @NaN@ — Symbol that represents "Not a Number"
not me casually handing you literal infinity and the void itself as valid inputs 🙈 use responsibly bestie 💖

💅 COMMANDS 💅

okay so wcalc has a whole little command language, and bestie, you're gonna want to know all of it. These are the commands that are supported in wcalc. Periodt. ✨

  • \pXXX — sets the precision, aka how many decimal places get displayed, to be XXX. This only changes the output, not the internal representation. If precision is -1, the number of decimal places shown depends on the value. Default is -1. 💅
  • \e or \eng or \engineering — rotates between always using scientific notation, never using scientific notation, and choosing to use scientific notation when it's convenient. You can also give it an argument that's one of always, never, or automatic to pick a mode directly. 🌈
  • \help or ? — displays a help screen. iconic. 👑
  • \prefs — prints out the current preference settings.
  • \li or \list or \listvars — prints out the currently defined variables.
  • \r or \radians — toggles between using and not using radians for trigonometric calculations.
  • \cons or \conservative — toggles accuracy guards. Here's the tea: because of the way floating point numbers are stored in computers, some numbers can't be represented exactly (like 0.1). Because of that, calculating with those numbers can produce results that aren't exactly correct, but are off from the correct answer by a very small value (smaller than the floating point value can represent accurately). For example, the calculation of 1-.9-.1 can return an extremely small number that isn't zero but is less than what can be represented accurately, so for all intents and purposes it's 0. The accuracy guard feature rounds numbers to zero if they're less than the representable accuracy of the floating point number. But sometimes numbers that small or smaller need to be displayed, so you should turn the accuracy guard off. Alternatively, you could increase the number of internal bits, which makes it possible to represent numbers with more accuracy. 🫶
  • \p or \picky or \l or \lenient — toggles variable parsing rules. When wcalc is "picky", it complains if you use undefined variables. When it's "lenient", wcalc assumes a value of 0 for undefined variables. 👑
  • \re or \remember or \remember_errors — toggles whether or not expressions that produce errors are remembered in the history.
  • \pre or \prefix or \prefixes — toggles the display of prefixes for hexadecimal, octal, and binary output.
  • \b or \bin or \binary — results are printed in binary (base 2). Numbers printed in binary have a prefix of 0b unless the \prefixes command is used.
  • \d or \dec or \decimal — results are printed in decimal (base 10). This option is the default, and it doesn't have a default prefix to indicate that numbers are in base 10.
  • \h or \x or \hex or \hexadecimal — results are printed in hexadecimal (base 16). Numbers printed in hexadecimal have a prefix of 0x unless the \prefixes command is used.
  • \o or \oct or \octal — results are printed in octal (base 8). Numbers printed in octal have a prefix of 0 unless the \prefixes command is used.
  • \round none|simple|sig_fig — wcalc can try to warn you when numbers have been rounded in the output display. It has two methods of keeping track: either by using significant figures (sig_fig), or by a simple digit-counting algorithm. Rounding in the command-line version is shown by a tilde before the equals sign (~=). Rounding in the GUI version is shown by changing the text color to red. In some cases, wcalc may think the number has been rounded even if it shouldn't have been necessary (this is because of the way floating point numbers are represented internally). 😭
  • \dsepX — sets the decimal separator character to be X.
  • \tsepX — sets the thousands-place separator character to be X.
  • \idsepX — sets the input-only decimal separator character to be X.
  • \itsepX — sets the input-only thousands-place separator character to be X.
  • \hlimitX — sets the limit (X) on the length of the history.
  • \open filename.txt — loads file filename.txt.
  • \save filename.txt — saves the current session and variable list to a file, filename.txt.
  • \bitsXXXX — sets the number of bits of precision that will be used to internally represent numbers to be XXXX. The default is 1024. Set it higher if you need more precision, set it lower if you want to use less memory.
  • \ints — toggles whether long integers will be abbreviated or not. This conflicts with engineering notation for large numbers, but not for decimals.
  • \prefs or \preferences — displays the current preference settings.
  • \convert unit1 unit2 — converts the previous answer from unit1 to unit2.
  • \store variablename — saves the specified variable in the preload file, ~/.wcalc_preload
  • \explain object — explains the specified object. The object can be a variable, constant, function, or command.
  • \verbose — verbose mode displays the expression to be calculated before calculating it.
  • \del or \delim or \delimiters — display delimiters in numerical output.
  • \cmod — toggle between C-style modulus operation and a more flexible method.
  • \color — toggles the use of color in the commandline output.

🎀 PREFERENCES 🎀

okay so bestie, wcalc can remember your whole vibe between sessions if you want it to — it just needs a little home for your settings, and that home is ~/.wcalcrc 💖

The format of the file is that each line is either blank or an assignment. Comments are ignored, and are defined as anything to the right of and including a hash mark (#). Assignments are of the form:

key=value

and here are literally all the keys you can use, no gatekeeping:

  • precision — a number that sets your display precision. It's the same energy as the \P command, where -1 means "auto" and anything else is however many decimal places you want. 🌸 Heads up though: this does not touch the behind-the-scenes precision. It's purely a glow-up for the display.
  • show_equals — either true ("yes" or "true") or false (anything else, which, rude, but okay). Same as the --quiet argument. It decides whether your answers start with an equals sign or not.
  • engineering — either "always", "never", or "automatic". Same as the \engineering command. Says whether answers show up in engineering notation or not.
  • use_radians — either true ("yes" or "true") or false (anything else). Same as the \radians command. Tells your trig functions whether to take radians or degrees.
  • print_prefixes — either true ("yes" or "true") or false (anything else). Same as the \prefixes command. Says whether base prefixes (like 0x for hex numbers, bestie) get used when showing output.
  • save_errors — either true ("yes" or "true") or false (anything else). Same as the \remember_errors command. Says whether lines with a syntax error get added to the history or not. 💀
  • precision_guard — either true ("yes" or "true") or false (anything else). Same as the \conservative command. Says whether the display tries to eliminate numbers too small to be accurate (hopefully those are only errors made by the binary approximation of the inputs, not you being wrong 💅).
  • print_integers — either true ("yes" or "true") or false (anything else). Same as the \ints command. Says whether whole integers get printed un-abbreviated or not. ⚠️ This conflicts with engineering notation for large integers — but not for decimals, so no drama there.
  • print_delimiters — either true ("yes" or "true") or false (anything else). Same as the \delimiters command. Says whether delimiters get added to output when displaying.
  • thousands_delimiter — uses the next character after the equals sign as its value. Same as the \tsep command. Says what the thousands delimiter is, and it can affect output if print_delimiters is enabled.
  • decimal_delimiter — uses the next character after the equals sign as its value. Same as the \dsep command. Says what the decimal delimiter is.
  • input_thousands_delimiter — uses the next character after the equals sign as its value. Same as the \itsep command. Says what the input-only thousands delimiter is, and it cannot affect output.
  • input_decimal_delimiter — uses the next character after the equals sign as its value. Same as the \idsep command. Says what the input-only decimal delimiter is, and it cannot affect output.
  • history_limit — either "no", for no limit (living freely ✨), or a number. Same as the \hlimit command.
  • output_format — either decimal, octal, binary, hex, or hexadecimal.
  • rounding_indication — either no, simple, or sig_fig. Same as the \rounding command.
  • c_style_mod — either true ("yes" or "true") or false (anything else). Same as the \cmod command. Says whether the modulo operator (%) behaves like it does in the C programming language, or whether it uses a more flexible method. This only affects modulo operations where negative numbers are involved. fr fr, here's the receipts — with c_style_mod set to true (the default):
-340 % 60 == -40; 340 % -60 == 40; -340 % -60 == -40

However, with c_style_mod set to false:

-340 % 60 == -40; 340 % -60 == -20; -340 % -60 == 20
  • color — either true ("yes" or "true") or false (anything else). Same as the \color command. Says whether the commandline interface uses color in its output or not. 🌈

💅 colors[XXX] 💅

  • (bold)red
  • (bold)green
  • (bold)yellow
  • (bold)blue

  • (bold)cyan
  • (bold)white

The XXX must be one of the following values:

  • conversion_category
  • conversion_unit
  • prompt
  • approx_answer
  • exact_answer
  • err_location
  • err_text
  • pref_name
  • pref_val
  • pref_cmd
  • status
  • var_name
  • var_desc
  • subvar_name
  • explanation

🌸 PRELOAD 🌸

Wcalc uses a file, ~/.wcalc_preload, to store persistent information between instances. Typically, this is used to store variables that are frequently defined — your ride-or-die constants, basically. 🫶

This file can be edited by hand with a standard text editor, no special tooling required. There's also a command within wcalc (\store) to append a variable definition to the end of this file. And here's the slay: any variable defined in this file is defined and available for use in any subsequent invocation of wcalc. ✨

okay that's genuinely the whole page, we ate and left no crumbs 🍓 and that lil <pink>wcalc(1)</pink> footer stamp you'd normally see down at the bottom is just this manual page's source and version tag (plus its date) — consider it the little signature on the masterpiece. go forth and compute, main character 💅💜
