  • The fp package provides fixed point arithmetic with high precision
  • The pgfmath package belongs to the PGF/TikZ package and provides many functions and a good parser
  • LuaLaTeX is a version of LaTeX which allows programming calculation in the programming language Lua

Here, let's work with the pgfmath package, as we already worked with TikZ, and it's better documented than the other options.

How to do it...
