RapidEvaluator - Version 1.1 The RapidEvaluator Delphi component is a real COMPILER of the mathematical expressions (formulas), such as "SIN(0.5)+COS(x)*2". It checks the expression syntax and generates the real machine code for evaluating given formula. The code generated is optimized to use FPU in order to achieve the maximal speed of calculations: it's even up to 2 TIMES FASTER THAN DELPHI'S 32-bit code. To satisfy your personal needs you can add external user-defined variables and functions in addition to built-in ones. Functions can have any number of parameters. Use RapidEvaluator to calculate formulas that is unknown at the stage of program compilation, for example to plot and tabulate functions, to make numerical computations and so on. Package contains two demo projects: equation plotting example and expression calculator.
