ANY, ALL(3clc) OpenCL Manual ANY, ALL(3clc)


any,_all - Test for sign bit.

int any(igentype x);

int all(igentype x);


any returns 1 if the most significant bit in any component of x is set; otherwise returns 0.

all returns 1 if the most significant bit in all components of x is set; otherwise returns 0.


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 argument type igentype refers to signed integer types, i.e. char, charn, short, shortn, int, intn, long, and longn. n is 2, 3, 4, 8, or 16.
