Description 

Author

Miles Kaufmann

This class can be used to safely evaluate mathematical expressions.

The class can take an expression in a text string and evaluate it by replacing values of variables and calculating the results of mathematical functions and operations.

It supports implicit multiplication, multivariable functions and nested functions.

It can be used to evaluate expressions from untrusted sources. It provides robust error checking and only evaluates a limited set of functions.

It could be used to generate graphs from expressions of formulae.
