TFunctionParser is an Automation/COM server that parses mathematical functions and evaluates them at runtime. About 100 functions and operations are predefined. Users can define functions, variables and constants. Features: -Algebraic syntax, not case sensitive -Parentheses () -Floating point numbers -Support of hexadecimal numbers -Angles in radians, degrees or gons -Userdefined variablenames (default: x, y, z and t) -Implemented mathematical constants -Userdefined constants -More than 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
