NAME¶

any,_all - Test for sign bit.

¶

DESCRIPTION¶

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.

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 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.
