I don't think that's appropriate for sharing between different types. The
inputs for sin include many outside the range of float (which probably
illustrates how unrepresentative they are of typical usage of sin), and we
don't want the float test to have lots of infinities tested.
Sharing inputs between sinf, cosf and sincosf may make much more sense.
