Hi Piotr,
double CDECL MSVCRT_atan( double x )
{
- if (!isfinite(x)) *MSVCRT__errno() = MSVCRT_EDOM; return atan(x); }
I've done a little more testing. The function is not setting errno in INF and -INF case. It does set errno to EDOM when argument is NAN.
Thanks for pointting out! Sorry I missed it. Sending a patch.
Regards, Zheng
