Fixed comment in Math.h

// 1. If both types are integral or floating-point, the larger type is selected.

// 2. If one type is integral and the other floating-point, the floating-point type is selected.

// This is necessary only due to the limitations of nvcc. Note that clang and gcc

// can handle automatic promotion using a single-type template, exactly like

// std::min and std::max are implemented in STL.

// Casting both arguments to the same type is necessary because std::min and std::max

// are implemented as a single-type template.
