NAME
     isgreater - test if x greater than y

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

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


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

RETURN VALUES
     Upon successful completion, the  isgreater()  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.
