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.
