/* Short algorithm description:

* 1) if |x|==0: sin(x)=x,
* cos(x)=1.
* 2) if |x|<2^-27: sin(x)=x-x*DP_SMALL, raising underflow only when needed,
* cos(x)=1-|x|.
* 3) if |x|<2^-5 : sin(x)=x+x*x^2*DP_SIN2_0+x^5*DP_SIN2_1,
* cos(x)=1+1*x^2*DP_COS2_0+x^5*DP_COS2_1
* 4) if |x|< Pi/4: sin(x)=x+x*x^2*(S0+x^2*(S1+x^2*(S2+x^2*(S3+x^2*S4)))),
* cos(x)=1+1*x^2*(C0+x^2*(C1+x^2*(C2+x^2*(C3+x^2*C4)))).
* 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:
* sign_sin = sign(x) * (-1.0)^(( n >>2)&1)
* sign_cos = (-1.0)^(((n+2)>>2)&1)
* poly_sin = ((((S4*t^2 + S3)*t^2 + S2)*t^2 + S1)*t^2 + S0)*t^2*t+t
* poly_cos = ((((C4*t^2 + C3)*t^2 + C2)*t^2 + C1)*t^2 + C0)*t^2*s+s
* if(n&2 != 0) {
* using cos(t) and sin(t) polynomials for |t|<Pi/4, results are
* cos(x) = poly_sin * sign_cos
* sin(x) = poly_cos * sign_sin
* } else {
* sin(x) = poly_sin * sign_sin
* cos(x) = poly_cos * sign_cos
* }
* 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/cos(+-0) = +-0/1 not raising inexact/underflow,
* sin/cos(subnormal) raises inexact/underflow,
* sin/cos(min_normalized) raises inexact/underflow,
* sin/cos(normalized) raises inexact,
* sin/cos(Inf) = NaN, raises invalid, sets errno to EDOM,
* sin/cos(NaN) = NaN.
