+/*
+ ALGORITHM DESCRIPTION:
+
+ 1) Range reduction to [-Pi/4; +Pi/4] interval
+ a) Grab sign from source argument and save it.
+ b) Remove sign using AND operation
+ c) Getting octant Y by 2/Pi multiplication
+ d) Add "Right Shifter" value
+ e) Treat obtained value as integer S for destination sign setting.
+ SS = ((S-S&1)&2)<<30; For sin part
+ SC = ((S+S&1)&2)<<30; For cos part
+ f) Change destination sign if source sign is negative
+ using XOR operation.
+ g) Subtract "Right Shifter" (0x4B000000) value
+ h) Subtract Y*(PI/2) from X argument, where PI/2 divided to 4 parts:
+ X = X - Y*PI1 - Y*PI2 - Y*PI3 - Y*PI4;
+ 2) Polynomial (minimax for sin within [-Pi/4; +Pi/4] interval)
+ a) Calculate X^2 = X * X
+ b) Calculate 2 polynomials for sin and cos:
+ RS = X * ( A0 + X^2 * (A1 + x^2 * (A2 + x^2 * (A3))));
+ RC = B0 + X^2 * (B1 + x^2 * (B2 + x^2 * (B3 + x^2 * (B4))));
+ c) Swap RS & RC if if first bit of obtained value after
+ Right Shifting is set to 1. Using And, Andnot & Or operations.
+ 3) Destination sign setting
+ a) Set shifted destination sign using XOR operation:
+ R1 = XOR( RS, SS );
+ R2 = XOR( RC, SC ). */
