NAME
     isgreaterequal - test if x greater than or equal to y

SYNOPSIS
     c99 [ flag... ] file... -lm [ library... ]
     #include 

     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 relation-
     ships  (less, greater, and equal) is true. Relational opera-
     tors 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) ver-
     sion of a relational operator. It facilitates writing  effi-
     cient  code  that  accounts for quiet NaNs without suffering
     the invalid floating-point exception. In the  SYNOPSIS  sec-
     tion,  real-floating  indicates  that  the  argument  is  an
     expression of real-floating type.
