k_cos.c 21 * 1. Since ieee_cos(-x) = ieee_cos(x), we need only to consider positive x.
23 * 3. ieee_cos(x) is approximated by a polynomial of degree 14 on
30 * |ieee_cos(x)-(1-.5*x +C1*x +C2*x +C3*x +C4*x +C5*x +C6*x )| <= 2
35 * ieee_cos(x) = 1 - x*x/2 + r
36 * since ieee_cos(x+y) ~ ieee_cos(x) - ieee_sin(x)*y
37 * ~ ieee_cos(x) - x*y,
38 * a correction term is necessary in ieee_cos(x) and hence
