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	excep‐
       tion 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 excep‐
       tion 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.
