* 1) if |x| == 0: return x.

* 3) if |x| < 2^-5 : return x+x^3*DP_SIN2_0+x^5*DP_SIN2_1.
* 4) if |x| < Pi/4: return x+x^3*(S0+x^2*(S1+x^2*(S2+x^2*(S3+x^2*S4)))).
* 5) if |x| < 9*Pi/4:
* 5.1) Range reduction: k=trunc(|x|/(Pi/4)), j=(k+1)&0x0e, n=k+1,
* t=|x|-j*Pi/4.
* 5.2) Reconstruction:
* s = sign(x) * (-1.0)^((n>>2)&1)
* if(n&2 != 0) {
* using cos(t) polynomial for |t|<Pi/4, result is
* s * (1.0+t^2*(C0+t^2*(C1+t^2*(C2+t^2*(C3+t^2*C4))))).
* } else {

* s * t * (1.0+t^2*(S0+t^2*(S1+t^2*(S2+t^2*(S3+t^2*S4))))).
* }
* 6) if |x| < 2^23, large args:
* 6.1) Range reduction: k=trunc(|x|/(Pi/4)), j=(k+1)&0xfffffffe, n=k+1,
* t=|x|-j*Pi/4.
* 6.2) Reconstruction same as (5.2).
* 7) if |x| >= 2^23, very large args:
* 7.1) Range reduction: k=trunc(|x|/(Pi/4)), j=(k+1)&0xfffffffe, n=k+1,
* t=|x|-j*Pi/4.
* 7.2) Reconstruction same as (5.2).
* 8) if x is Inf, return x-x, and set errno=EDOM.
* 9) if x is NaN, return x-x.
*
* Special cases:
* sin(+-0) = +-0 not raising inexact/underflow,
* sin(subnormal) raises inexact/underflow,
* sin(min_normalized) raises inexact/underflow,
* sin(normalized) raises inexact,
* sin(Inf) = NaN, raises invalid, sets errno to EDOM,
* sin(NaN) = NaN.
