In fact the slightly older POSIX standard > I've got here (not online) says that more explicitly: > > "If the value of x is not in the range [−1,1], and is not ±Inf or NaN, > either 0.0 or NaN shall be returned and errno shall be set to [EDOM]. > > If x is NaN, NaN shall be returned and errno may be set to [EDOM]. > > If x is ±Inf, either 0.0 shall be returned and errno set to [EDOM], or NaN > shall be returned and errno may be set to [EDOM]." > > I assume in the more recent standard they decided to make it more general - > not necessarily 0.0 but any value as long as it's implementation-defined. > But that can certainly be 0.0. -- You are receiving this mail because: You are on the CC list for the bug.
