7.12.14.3 The isless macro

Synopsis

1

#include <math.h>
int isless(real-floating x, real-floating y);

Description

2

The isless macro determines whether its first argument is less than its second argument. The value of isless(x, y) is always equal to (x) < (y); however, unlike (x) < (y), isless(x, y) does not raise the “invalid” floating-point exception when x and y are unordered.

Returns

3

The isless macro returns the value of (x) < (y).
