✨ GIAC ✨

okay bestie, buckle up, because we're about to talk about giac — a whole computer algebra system, living in your terminal, and it is that girl 💅 (this page comes from the General Commands Manual, btw, so you know it's official)

🌸 NAME 🌸

giac — computer algebra system 💖 (yes, that's the whole vibe, a whole CAS just vibing)

🦋 SYNOPSIS 🦋

giac [options] files
icas [options] files
xcas  files
cas_help  keyword

🎀 DESCRIPTION 🎀

so giac is an advanced symbolic and numeric calculator by Bernard Parisse, and honestly? iconic. 👑

The console interface is named icas — or equivalently giac, same energy, two names, no cap. The matching GUI program is called xcas. 🖥️✨

These programs have extensive html documentation, so if you're lost, there's lore. You can also pull up help about a keyword like this:

0>> ?gcd
Returns the greatest common divisor of 2 polynomials of several variables
or of 2 integers or of 2 rationals.
(Intg(a) or Poly),(Intg(b) or Poly)
gcd(45,75);gcd(15/7,50/9);gcd(x^2-2*x+1,x^3-1);gcd(t^2-2*t+1,t^2+t-2);
gcd((x^2-1)*(y^2-1)*z^2,x^3*y^3*z+(-(y^3))*z+x^3*z-z)
lcm,euler,modgcd,ezgcd,psrgcd,heugcd,Gcd

look at her go, the way that ?gcd just delivered 😭💖

💅 OPTIONS 💅

  • --version — shows you the version of the program. that's it, that's the whole thing, short and sweet ✨
  • --texmacs — so you can call giac/icas from Texmacs 🎀
  • --emacs — so you can call giac/icas from Emacs 🌈
  • --sage — so you can call giac from Sage 🌸

👀 SEE ALSO 👀

The programs are documented fully by the GIAC/XCAS manual in html format, living right here:

/usr/share/giac/doc

And C++ programers (their spelling, not mine, bestie 🫶) will find some informations about the giac library in the info manual. iykyk 📖
