NAME

islessequal - test if x is less than or equal to y

SYNOPSIS

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

#include

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

DESCRIPTION

The islessequal() macro determines whether its first argu-

ment is less than or equal to its second argument. The value

of islessequal(x, y) is equal to (x) < (y); however, unlike

(x) < (y), islessequal(x, y) does not raise the invalid

floating-point exception when x and y are unordered.

RETURN VALUES

Upon successful completion, the islessequal() 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 relation-

ships (less, greater, and equal) is true. Relational opera-

tors can raise the invalid floating-point exception 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) ver-

sion of a relational operator. It facilitates writing effi-

cient code that accounts for quiet NaNs without suffering

the invalid floating-point exception. In the SYNOPSIS sec-

tion, real-floating indicates that the argument is an

expression of real-floating type.
