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.SPECIFICATION¶
