CMATH is a comprehensive library for complex-number arithmetics and mathematics. The following features make CMATH an ideal replacement for the unit Complex coming with Delphi: 1. High-performance implementation in machine code leads to superior speed. 2. Accuracy and safety are greatly enhanced. 3. Each of the floating-point accuracies (complex(float), complex(double), and complex(extended)) is given its own, individually optimized treatment. 4. Polar coordinates (magnitude;angle) are supported in addition to the usual cartesian coordinates (real;imaginary). The Shareware edition is optimized for PentiumXX, while maintaining compatibility with AMD processors (Athlon) and down to 486DX. This version is for Delphi 2010.
