NAME
       isgreater - test if x greater than y

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

       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 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.
