SYNOPSIS
#include <math.h>
int islessequal(
floating-type x,
floating-type y);
PARAMETERS
floating-type Specifies the floating-type of x.
x Specifies a value of type floating-type.
floating-type Specifies the floating-type of y.
y Specifies a value of type floating-type.
DESCRIPTION
The islessequal( ) macro determines whether its first argument is less than or equal to its second
argument. The value of the islessequal( ) macro is always equal to (x)<=(y); however, unlike
(x)<=(y), the islessequal( ) macro does not raise the invalid exception when x and y are unor-
dered.
The arguments must be of floating type.
NOTES
This macro is implemented only for the IEEE_float floating-point option. Applications using
this macro cannot be compiled if the specified floating-point option is Tandem_float.
RETURN VALUES
Upon successful completion, the islessequal( ) macro returns the value of (x)<=(y). If x or y is
NaN, 0 (zero) is returned.
ERRORS
No errors are defined.
