by Marianne H. Goeltl-Schuberth
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.
| 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 and FALSE
|| Implemented mathematical constants i, e, pi, C
| Userdefined constants that may be expressions themselves
||Userdefined constants (only real xor imaginary numbers)
| About 80 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)
| One special userfunction: YOUR own code is evaluated
| Easy to use |
