@hackage ParserFunction0.0.8

ParserFunction provides utilities for parsing and evaluating mathematical expressions. The central parsing function in this package is stringToExpr, which parses a string-expression and returns a maybe expression tree. This tree is suitable for performing symbolic manipulation. Expressions can then be evaluated using the function evalExpr. If you wish to evaluate a string-expression without any intermediate operations, simply use the function evalString. Examples of these functions can be seen by viewing the source code of this module.
