__finite -- test for infinity

Synopsis

#include <math.h>

int __finite(double arg);

Description

__finite() has the same specification as isfinite() in POSIX 1003.1-2001 (ISO/IEC 9945-2003), except that the argument type for __finite() is known to be double.

__finite() is not in the source standard; it is only in the binary standard.
