BITSELECT(3clc)

💖 BITSELECT(3clc) — the OpenCL Manual, but make it cute 💖

okay bestie, pull up a chair, we're doing bitselect from the OpenCL manual and it's genuinely lowkey iconic 🎀

---

✨ NAME ✨

bitselect — each bit of the result is the corresponding bit of a if the corresponding bit of c is 0 🫶

gentype bitselect(gentype a, gentype b, gentype c);

halfn bitselect (halfn a, halfn b,
halfn c)      // if half extension
enabled

---

🌸 DESCRIPTION 🌸

okay so here's the whole vibe: every single bit of the result is the corresponding bit of a if the corresponding bit of c is 0 💅 otherwise? it's the corresponding bit of b. that's it. that's the function. a little bit-picking queen 👑

🦋 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. so like, NaNs are not the drama here, periodt 💀

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 gentype can be char, charn, uchar, ucharn, short, shortn, ushort, ushortn, int, intn, uint, uintn, long, longn, ulong, ulongn, float, floatn, double, and doublen. that's the whole roster, no cap 👑
