TFunctionParser is an Automation/COM server that parses mathematical functions and evaluates them at runtime. About 90 functions and operations are predefined. Users can define functions, variables and constants.

Features:
-Algebraic syntax, not case sensitive
-Parentheses ()
-Floating point numbers
-Angles in radians, degrees or gons
-Userdefined variablenames (default: x, y, z and t)
-Implemented mathematical constants
-Userdefined constants
-About 90 predefined mathematical functions and operations in TFunctionParser
-Userdefined functions based on the predefined ones (macros)
-functions can be inserted into other functions (e.g. 'f(g(sin(1/x))+x/2)*h(g(x-1);pi)')
-Easy to use
