// CUDA lets us use various std math functions on the device side.  This file
// works in concert with __clang_cuda_math_forward_declares.h to make this work.
//
// Specifically, the forward-declares header declares __device__ overloads for
// these functions in the global namespace, then pulls them into namespace std
// with 'using' statements.  Then this file implements those functions, after
// their implementations have been pulled in.
//
// It's important that we declare the functions in the global namespace and pull
// them into namespace std with using statements, as opposed to simply declaring
// these functions in namespace std, because our device functions need to
// overload the standard library functions, which may be declared in the global
// namespace or in std, depending on the degree of conformance of the stdlib
// implementation.  Declaring in the global namespace and pulling into namespace
// std covers all of the known knowns.
