...and Metal all have defined semantics for NaNs which include not propagating them through min/max. GLSL (OpenGL) is the odd one out in this area. —Owen -------------- next part -------------- An HTML attachment was scrubbed...

Hi Carter, I would strongly advise you against this direction. I’m aware of two directions that existing languages go in defining min/max operations: - IEEE 754, C, Fortran, Matlab, OpenCL, and HLSL all define it not to propagate NaNs - C++ (std::min/std::max) and OpenGL define it in the trinary operator manner: (a < b) ? a : b What you’re proposing does not match any existing languages
