may be available only with certain extended compilers.
Compute the sine of
x,
where the argument is measured in radians. Unlike the normal sine
function, the argument is reduced to the interval [-pi,+pi]
as
x = TWO_PI * n + r
where TWO_PI is the best floating-point approximation to 2pi
in working precision. The function value is then sin(r).
If the argument is finite, its sine is returned. Otherwise, a NaN
is returned.
If the argument is a NaN, errno is set to EDOM, and the
argument is returned. If the argument is +Infinity or -Infinity,
errno is set to EDOM, and a quiet NaN is returned.
