Descrizione
The current implementations of isnan are limited to float, double, and long double. We should add support for the remaining types (float16, bfloat16, and float128).
Additionally, the existing implementations currently rely on __builtin_isnan. I think refactoring them to use fputil would be better, especially since issignaling already uses fputil.
