ExacMath - High Precision Math Library

High Precision Math Library called ExacMath. This is a commercial 32 or 64 bit version running on Windows XP, Windows 7 or 8. It uses Dekkers Algorithm and a table of minmax polynomial approximation to increase the speed and accuracy of the results. In most cases one will get last bit accuracy. There are 4 data types, real80(long double), duad(106 bits of precision), quad(128 bits of precision), and mpad(multiple precision). A programmers reference manual along with 4 manuals describing how to use each function is included. Code includes an elaborate exception handling method. Available for use on Microsoft Visual C++ 6.0. or higher. The sample code are the actual test programs for accuracy and timining. Will be available in the fall of 2015.
