Mathematical formula compiler&evaluator  VCL Component for Delphi. TRyFormulaEval is a native Delphi component designed to evaluate mathematical formulas. Performace of this evaluation is improved by compiling the formula to assembler code, internally. TRyFormulaEval implements parse onceevaluate many times type of parsing for mathematical expressions given as strings. It allows creation of custom variables and functions to be used in the expressions; once defined, functions can be redefined in runtime and extremely fast, resulting a very powerful tool. Its internal arithmetic uses #Extended# storage for floating point numbers. Variable values can be set in three different ways: OnFindVariable event oriented, reference by name, reference by index. Thread safe. [more] Added: 10112000  Version: 2.0  Downloads: 1871/1871/9

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 chisquare distribution). registration fee US$ 12, sources for US$ 80 Added: 13091998  Version: 1.0  Downloads: 2234/2234/0
