Detailed Description
Scalar helpers and numeric limits that compile for both host and device.
std::min, std::max, std::clamp and std::numeric_limits are constexpr host functions. nvcc rejects them in device code unless every translation unit is compiled with –expt-relaxed-constexpr, and a standard library update can make them unusable on a device altogether (libstdc++ 14's std::clamp asserts through a host-only function). The library uses these instead, everywhere under Source/; Scripts/CheckDeviceMath.py enforces that.
