sine, cosine, and square
roots make up a vast majority of 3D math processes
these very functions are the most time consuming of all x87 (FPU)
so I sent them to boot camp and whipped 'm into shape
NOW ! - Cosine and Sine for any
angle in 27 clocks !!!
(fcos and fsin take up to 124 plus more for angles over 45
degrees (PI/4 radians))
bSin and bCos functions work equally fast on ANY angle this side
of infinity (negative or positive)
Tests prooved these bMath functions average more then 4 times
faster then FPU functions !!!
PLUS ! - "Snappy"
sine and cosine in 14 clocks !!!
perfect for many uses (smooth triangle manipulation & etc)
approaching 10 times the speed of FPU functions !!!
ALSO ! - Square Roots in 23
(fsqrt takes 70)
bSqrt is over 3 times faster !!!
