SYNOPSIS
#include <math.h>
int isgreaterequal(
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 isgreaterequal() macro determines whether its first argument is greater than or equal to its
second argument. The value of the isgreaterequal() macro is always equal to (x)>=(y); how-
ever, unlike (x)>=(y), the isgreaterequal() macro does not raise the invalid exception when x
and y are unordered.
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 isgreaterequal() macro returns the value of (x)>=(y). If x or y
is NaN, 0 (zero) is returned.
ERRORS
No errors are defined.
