s_tanpi.c 28 * tanpi(x) computes tan(pi*x) without multiplication by pi (almost). First,
29 * note that tanpi(-x) = -tanpi(x), so the algorithm considers only |x| and
33 * 1. For small |x|, tanpi(x) = pi * x where a sloppy threshold is used. The

49 * tanpi(x) = tan(pi*(j0+r)) = ---------------------------- = tanpi(r)
54 * 4. For |x| >= 0x1p(P-1), |x| is integral and tanpi(x) = copysign(0,x).
