NAME

       islessgreater - Compare of (x < y) || (x > y).

       int islessgreater(float x, float y);

       intn islessgreater(floatn x, floatn y);

       int islessgreater(double x, double y);

       longn islessgreater(doublen x, doublen y);

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

DESCRIPTION

       Returns the component-wise compare of (x < y) || (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.
