ALGORITHM DESCRIPTION:
|
|
|
|
1) Range reduction to [-Pi/2; +Pi/2] interval
|
|
a) Grab sign from source argument and save it.
|
|
b) Remove sign using AND operation
|
|
c) Getting octant Y by 1/Pi multiplication
|
|
d) Add "Right Shifter" value
|
|
e) Treat obtained value as integer for destination sign setting.
|
|
Shift first bit of this value to the last (sign) position
|
|
f) Change destination sign if source sign is negative
|
|
using XOR operation.
|
|
g) Subtract "Right Shifter" value
|
|
h) Subtract Y*PI from X argument, where PI divided to 4 parts:
|
|
X = X - Y*PI1 - Y*PI2 - Y*PI3 - Y*PI4;
|
|
2) Polynomial (minimax for sin within [-Pi/2; +Pi/2] interval)
|
|
a) Calculate X^2 = X * X
|
|
b) Calculate polynomial:
|
|
R = X + X * X^2 * (A3 + x^2 * (A5 + ......
|
|
3) Destination sign setting
|
|
a) Set shifted destination sign using XOR operation:
|
|
R = XOR( R, S );
