// This file forward-declares of some math functions we (or the CUDA headers)
// will define later.  We need to do this, and do it before cmath is included,
// because the standard library may have constexpr math functions.  In the
// absence of a prior __device__ decl, those constexpr functions may become
// implicitly host+device.  host+device functions can't be overloaded, so that
// would preclude the use of our own __device__ overloads for these functions.
