financial functions (NetPresentValue, Payment, SLNDepreciation, ...),
sorting, discrete math (quicksort, insertion sort, equivalence classes, ...),
miscellaneous (IsNaN, Get/Set87ControlWord, GetRoundMode, ...)
Engineering Mathematics

optimization (simplex, powell, ...),
root finding, non-linear equations
Statistics and Probability
statistics (min, max, sum, mean, stddev, skew, kurtosis, ...),
probability (binomial, pnorm, randg, factorial, Stirling, ...)
curve fitting, regression, least squares, data modeling
Secret Message Cryptography and Multiple-Precision Arithmetic
((A + B) * (C + D)) Parsers and Mathematical Expression Evaluators
Notes: 1. Definitions for all Delphi Math unit functions are listed for quick reference.
2. Many of the functions listed here are Pascal functions,
which should be easily translated to Delphi.
3. Additional links can be found on many of the pages.
