The calculator and calculus packages define several instructions which allow us to realise algebraic operations and to evaluate elementary functions and derivatives in our documents.

The package’s main goal is to define the arithmetic and functional calculations need in the author’s package xpicture, but the numeric abilities of “calculator” and “calculus” may be useful in other contexts.

The author is Robert Fuster. The package is Copyright © 2012, 2014 Robert Fuster.
