isgreaterequal - test if x greater than or equal to y

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

SYNOPSIS

DESCRIPTION
The isgreaterequal() macro determines whether its first argument is
greater than or equal to its second argument. The value of
isgreaterequal(x, y) is equal to (x) >= (y); however, unlike (x) >=
(y), isgreaterequal(x, y) does not raise the invalid floating-point
exception when x and y are unordered.
RETURN VALUES
Upon successful completion, the isgreaterequal() 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
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) 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.
