Detailed Description

Library for parsing math expression strings.

This library basicaly does what every other parser does: turn infix notation to Reverse Polish and than calculate the result. The additional feature is that this library creates a structure (map) of the Reverse Polish so that it can be later used as a function. The call to the function is performed by setting the variables to a prior constructed math expression object. The goal is to have a fast calculation as close as possible to the speed of a hardcoded function.
