Math::Fibonacci(3pm)

💖 Math::Fibonacci 💖

okay bestie, pull up a chair, because today we're talking about the perl manual page for Math::Fibonacci — like, the User Contributed Perl Documentation one? yeah, that one. Fibonacci numbers, but make it perl. no cap, we're doing math and it's gonna slay. 🦋

---

✨ NAME ✨

Math::Fibonacci — it's Fibonacci numbers, babe. that's the whole vibe. 🌸

🎀 VERSION 🎀

$Revision: 1.5 $

that's it, that's the version, noted and archived, periodt. 💅

🌈 SYNOPSIS 🌈

okay so here's how you actually use it, copy-paste girlies rise:

use Math::Fibonacci qw(term series decompose);

my $term = term ( 42 );
my @series = series ( 42 );
my @sum = decompose ( 65535 );

look how cute that is. you import term, series, and decompose, then you just… ask for stuff. iconic behaviour honestly. ✨

🔥 DESCRIPTION 🔥

This module provides a few functions related to Fibonacci numbers. that's it, that's the summary, no essays, just vibes and numbers. 🧚

👑 EXPORTS ON REQUEST 👑

here's what you can ask it to hand over when you use it — bestie, they're opt-in, so you gotta name them yourself:

• term()
• series()
• decompose()
• isfibonacci()

(no commas between them in the original list, and honestly? we respect the chaos. 🙈)

💜 FUNCTIONS 💜

term($n)

Returns the $n-th term of the Fibonacci sequence. ✨

and here's the juicy part — it's computed with the fast algorithm:

F(n) ~ g^n/sqrt(5)

where g is the golden ratio, and that little ~ means "take the nearest integer". so it's not summing a billion tiny numbers, it just ✨ vibes ✨ its way to the answer. main character energy fr fr. 💅

series($n)

Computes and returns the first $n Fibonacci numbers. a whole lineup. a little squad. 🫶

decompose($int)

Decomposes $int into the sum of Fibonacci numbers. Returns the list of Fibonacci numbers. it takes your big number apart like unboxing haul and hands you back the pieces. 💖

isfibonacci($int)

Returns the sequence number of $int if it is a Fibonacci number — or a non-true value if it is not. so basically a vibe check for numbers: either it tells you where it sits in the lineup, or it simply does not. 😭

and that's the whole page, bestie!! this was Math::Fibonacci, documented for perl v5.36.0, dated 2022-10-15, and you read it top to bottom like a scholar. so proud. go compute some Fibonacci numbers and text me the results. mwah. 💖✨💅🦋🌸🎀
