NAME
       isfinite - test for finite value

SYNOPSIS
       #include <math.h>

       int isfinite(real-floating x);

DESCRIPTION
       The  isfinite() macro shall determine whether its argument has a finite
       value (zero, subnormal, or normal, and not infinite or NaN). First,  an
       argument	 represented  in a format wider than its semantic type is con‐
       verted to its semantic type. Then determination is based on the type of
       the argument.

RETURN VALUE
       The  isfinite()	macro shall return a non-zero value if and only if its
       argument has a finite value.

ERRORS
       No errors are defined.
