NAME
       isfinite - test for finite value

SYNOPSIS
       c99 [ flag... ] file... -lm [ library... ]
       #include <math.h>

       int isfinite(real-floating x);

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

RETURN VALUES
       The  isfinite() macro returns a non-zero value if and only if its argu‐
       ment has a finite value.

ERRORS
       No errors are defined.
