Announcement text: 
----------------------------------------------------------------------

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

My main goal is to define the arithmetic and functional calculations need in my 
package "xpicture" (http://www.upv.es/~rfuster/xpicture), but the numeric 
abilities of "calculator" and "calculus" may be useful in other contexts.
