NAME

isfinite - test for finite value

SYNOPSIS

c99 [ flag... ] file... -lm [ library... ]

#include

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 argument 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 argument has a finite value.

ERRORS

No errors are defined.
