BlitzInterpreter
BlitzInterpreter is a COM server for mathematical expressions parsing. It parses any text fragment (both single line and multiline) and returns the result of calculation. It supports variables, functions and constants management and contains a lot of basic preloaded functions and constants. Compiled in fully optimization mode, it will never be the slow part of your program. If you have a task to develop math expressions interpreter, we recommend to look at this. Our BlitzCalc is based on the BlitzInterpreter kernel.
