Genius Calculator
February 22, 2026 ยท View on GitHub
Genius calculator is a general purpose calculator and mathematics tool with many features.
For a manual, you can open a manual from the menu in the graphical version or you can type "manual" and enter in the genius command prompt. It will launch a browser with the manual (a text based browser if running the terminal version of genius). Alternatively you can read help/genius.txt for a text conversion of the manual.
Requirements: - lex (tested under flex) - yacc (tested under bison -y) - gmp (relatively new one required) - mpfr (relatively new one) - glib 2.41.1 And for the GNOME frontend you need: - gtk+ 3.21.4 - vte 2.91 - gtksourceview4 3.99.7
If you want to compile without the GNOME frontend, try the --disable-gnome argument to the ./configure script. You will miss out on the GUI stuff (which includes the plotting) but you can use all the rest nicely.
It's under GPL so read COPYING
Note: the gtkextra/ directory which includes the plotting widgetry is copyright: Adrian E. Feiguin feiguin@ifir.edu.ar and is under LGPL. It is somewhat modified from the stock version.
