NAME

       isgreater - test if x greater than y

SYNOPSIS

       #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
       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.
