Take a look into std.math:

I found this:
real sin(real x) @safe pure nothrow; /* intrinsic */
And these:
creal sin(creal z) @safe pure nothrow
{
creal cs = expi(z.re);
creal csh = coshisinh(z.im);
return cs.im * csh.re + cs.re * csh.im * 1i;
}
/** ditto */
ireal sin(ireal y) @safe pure nothrow
{
return cosh(y.im)*1i;
}
I don't see anything about ctfe. Maybe I didn't understand well
and sin is not evaluated at compile time. Can someone clarify
this?
Justly, you see a normal runtime function, and a CTFE function is
a normal runtime function(with some restrictions) that can be
interpreted at runtime.
static res = sin(4); //compile time
auto res = sin(4); //runtime
