Expression evaluator for functions of up to three variables, also supporting up to 6 parameters. Not an interpreter, but a quasi compiler for the functions, so it is fast for repeated evaluations. Demo included
Free for noncommercial and educational use

TFormulaTrans is a component which parses a mathematical formula and outputs the string in a form where it can be read by most of the expression Parsers which are available. Your average expression parser expects input in the form of (for example) X*

The TKAParser component is an expression parser, calculator and spread sheet engine. It can (1) Evaluate mathematical and string expressions that contain numbers, predefined variables and formulas. A mathematical expression may have any commonly used math functions. A string expression may have any commonly used string function. (2) Transparently track formula / variable dependencies. Consequently, the parser needs to re-evaluates a formula only when the value of a dependent variable changes, a feature that enables it to perform hundreds of complex expression evaluations every second. A caching mechanism further optimizes expression evaluation making the parser#well# Kick Ass! Work with any number of user defined functions. (3) Gracefully handle undefined variables by assigning default user defined value

The unit STATIS offers some of the most fundamental procedures of mathematical statistics. Along with the Gamma and the Beta function, all major types of distributions are implemented (normal, t, F, and chi-square distribution).
