UCalc Fast Math Parser is a 32-bit DLL component which allows programs to evaluate math expressions that are defined at run time. It supports conventional math operators and functions, as well as unlimited user operators, functions, and variables. User functions can be either a one-line definition, or a call-back to a function in your source-code. This parser also supports string functions and string arguments, customizable separators for international users, customizable syntax, extended precision, floating point even in non-decimal bases, and more. This component is suitable for heavy duty number crunching. This version includes direct support Delphi. The evaluation file is fully functional.
