NAME

       isgreater - Compare of x > y.

       int isgreater(float x, float y);

       intn isgreater(floatn x, floatn y);

       int isgreater(double x, double y);

       longn isgreater(doublen x, doublen y);

       int isgreater (half x, half y)   // if half
       extension enabled
       shortn isgreater (halfn x, halfn y)   // if half
       extension enabled

DESCRIPTION

       Returns the component-wise compare of x > y.

NOTES

       If an implementation extends this specification to support IEEE-754 flags or exceptions,
       then all built-in relational functions shall proceed without raising the invalid
       floating-point exception when one or more of the operands are NaNs.

       The built-in relational functions are extended with cl_khr_fp16(3clc) to include
       appropriate versions of functions that take half, and half{2|3|4|8|16} as arguments and
       return values.

       The function returns a 0 if the specified relation is false and a 1 if the specified
       relation is true for scalar argument types. These functions shall return a 0 if the
       specified relation is false and a - 1 (i.e. all bits set) if the specified relation is
       true for vector argument types.

       The relational functions isequal, isgreater, isgreaterequal, isless, islessequal, and
       islessgreater always return 0 if either argument is not a number (NaN).  isnotequal
       returns 1 if one or both arguments are not a number (NaN) and the argument type is a
       scalar and returns -1 if one or both arguments are not a number (NaN) and the argument
       type is a vector.
