TComplexParser (Delphi 6) - Invisible DELPHI component for evaluating mathematical functions.

TFunctionParser and TComplexParser are invisible Delphi component for evaluating mathematical functions. The function term is a user given String like `sin(x)*x`. The function term can be changed during runtime.These are the features of the latest version (TFunctionParser 6.x / TComplexParser 3.x). Older versions may differ. TFunctionParser TComplexParser Algebraic syntax, not case sensitive Parentheses () Floating point numbers (extended) Complex floating point numbers Angles in radians, degrees or gons Angles in radians Userdefined variable names (Default: x, y, z and t) Implemented mathematical constants e, pi, C, TRUE, FALSE and NaN Implemented mathematical constants i, e, pi, C Userdefined constants that may be expressions themselves Userdefined constants (only real xor imaginary numbers) Almost 90 predefined mathematical functions and operations More than 30 complex mathematical functions and operations Userdefined functions based on the predefined ones (macros): handle nested constructions like g(h(x+pi)/2) Userfunctions: YOUR own code is evaluated Easy to use
