s_cospi.c 28 * cospi(x) computes cos(pi*x) without multiplication by pi (almost). First,
29 * note that cospi(-x) = cospi(x), so the algorithm considers only |x|. The
32 * 1. For small |x|, cospi(x) = 1 with FE_INEXACT raised where a sloppy
45 * cospi(x) = cos(pi*(jj0+r))
48 * = +-cospi(r)
51 * cospi(r) is then computed via an appropriate kernel.
53 * 4. For |x| >= 0x1p(P-1), |x| is integral and cospi(x) = 1.
57 * cospi(+-0) = 1.
58 * cospi(n.5) = 0 for n an integer
