The package provides basic arithmetic operations to 8 decimal places for plain TeX or LaTeX. Results are exact when they fit within the digit limits. Along with the basic package is an optional extension that adds computation of sin, cos, log, sqrt, exp, powers and angles. These are also exact when theoretically possible and are otherwise accurate to at least 7 decimal places.

In addition, the package provides a stack-based programing environment.
