.................... //// * 9/20/2001 : Improvments are made to sin/cos code. ////
.................... //// The code now is small, much faster, ////
.................... //// and more accurate. ////
.................... //// * 2/21/2007 : Compiler handles & operator differently and does ////
.................... //// not return generic (int8 *) so type cast is done ////
.................... //// * 6/19/2010 : Divisions by constants converted to multiplication ////
.................... //// by its inverse to improve computation speed ////
.................... //// * 1/21/2011 : Constants used for double precision math updated ////
.................... //// Updated routines include 64 bit versions of cos, ////
.................... //// asin,atan,exp,log and dependant functions ////
.................... //// * 1/31/2011 : Optimized current 32-bit float routines for cos ////
.................... //// and log function ////
.................... //// * 6/13/2011 : Fixed PCD overload CEIL_FLOOR functions for values ////
.................... //// greater then 10000000 and less then -10000000 ////
