ANY(3clc)

✨ NAME ✨

ok so this is any, all from the OpenCL Manual (3clc) — and they're literally just vibing here to **test for sign bit 💅

int any(igentype x);

int all(igentype x);

---

🌸 DESCRIPTION 🌸

Bestie. Listen. Both of these functions are looking at the most significant bit of your components and going "hmm, is it set? 👀"

• any — returns 1 if the most significant bit in any component of x is set; otherwise returns 0. So like, one single component sets it and she's satisfied. Periodt.
• all — returns 1 if the most significant bit in all components of x is set; otherwise returns 0. Every single one. No exceptions. Main character energy.

🦋 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. Noted. Respectfully. 😌

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. cute extension, we love to see it 🎀

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