strtod(3c)/wcstod(3c) man pages should mention math.h
wcstod(3c) man pages there is this wording:
If the correct value is outside the range of representable values, ±HUGE_VAL, ±HUGE_VALF, or ±HUGE_VALL is returned (according to the sign of the value), a floating point overflow exception is raised, and errno is set to ERANGE.
The problem is that those constants (
HUGE_VALL) are not readily available when there is just
wchar.h included respectively (as suggested by the man pages synopsis) because they are defined in
math.h is not mentioned anywhere in either man page. We should change that.
