NAME
isless - test if x is less than y

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

int isless(real-floating x, real-floating y);

DESCRIPTION
The  isless()  macro determines whether its first argument is less than
its second argument.  The value of isless(x, y) is 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.

RETURN VALUES
Upon successful completion, the isless() macro returns the value of (x)
< (y).

If x or y is NaN, 0 is returned.

ERRORS
No errors are defined.

USAGE
The  relational	and  equality operators support the usual mathematical
relationships between numeric values. For any ordered pair  of  numeric
values,	exactly one of the relationships (less, greater, and equal) is
true. Relational operators can raise the invalid floating-point	excep‐
tion  when  argument values are NaNs. For a NaN and a numeric value, or
for two NaNs, just the unordered relationship is true. This macro is  a
quiet  (non-floating-point  exception  raising) version of a relational
operator. It facilitates writing efficient code that accounts for quiet
NaNs  without  suffering	 the  invalid floating-point exception. In the
SYNOPSIS section, real-floating	indicates  that	 the  argument	is  an
expression of real-floating type.
