ISGREATEREQUAL(3clc)

🌸 ISGREATEREQUAL 🌸

okay bestie, welcome to the OpenCL Manual page for isgreaterequal(3clc) 💖 — yes that's the manual name, yes it's a mouthful, no we're not renaming it, sit down, sip your strawberry matcha, we're doing math 🍓

---

✨ NAME ✨

isgreaterequal — literally just compares x >= y. that's it. that's the whole gig. 👑

here's every single flavor it comes in, and I mean every one:

int isgreaterequal(float x, float y);

intn isgreaterequal(floatn x, floatn y);

int isgreaterequal(double x, double y);

longn isgreaterequal(doublen x, doublen y);

int isgreaterequal (half x, half y)
// if half extension enabled
shortn isgreaterequal (halfn x, halfn
y)   // if half extension enabled

note the half ones only exist if half extension enabled, bestie. no extension, no half vibes. 🧚

---

💫 DESCRIPTION 💫

returns the component-wise compare of x >= y. so like, it goes down the list, checks each pair, and tells you how each one did. slay. ✨

🔥 NOTES 🔥

if an implementation extends this spec 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. like, they just keep it moving. no dramatic meltdown. 💅

the built-in relational functions get 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. tiny numbers, big energy. 🎀

now the important part, the return values, pay attention bestie:

• for scalar argument types: returns a 0 if the specified relation is false, and a 1 if the specified relation is true.
• for vector argument types: returns a 0 if the specified relation is false, and a - 1 (i.e. all bits set) if the specified relation is true.

and the group chat behavior of the whole relational crew:

isequal, isgreater, isgreaterequal, isless, islessequal, and islessgreater always return 0 if either argument is not a number (NaN). no cap.

isnotequal is the messy one (affectionate): it 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. 🙈
