We had to write a collection of FP It depends how the application handlers errors. errno is usually not set as specified. The library attempts to set the IEEE exception masks to report errors. This sometimes fails because gcc doesn't fully support IEEE. ANSI applications can't use IEEE features anyway. At best they can hope that HUGE_VAL is a good value and is returned when specified (it is), and that weird enough values are returned for range errors.
