ISGREATEREQUAL(3M) Mathematical Library Functions ISGREATEREQUAL(3M)

NAME

isgreaterequal - test if x greater than or equal to y

SYNOPSIS

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

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

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.
