FLOOR(3clc)

✨ FLOOR(3clc) ✨

okay bestie, welcome to the OpenCL Manual 💖 this is FLOOR(3clc) and it's literally one of the math girlies, she's giving "round down and chill" and honestly? obsessed.

🎀 NAME 🎀

floor — round to integer toward negative infinity, no cap.

gentype floor(gentype );

like. that's her. that's the whole vibe. 🦋

---

💅 DESCRIPTION 💅

floor rounds to an integral value using the round to negative infinity rounding mode.

so if you're sitting at like 2.9 and you call floor, you get 2. she does NOT round up, she rounds down, always, toward negative infinity, periodt. 📉

🌸 NOTES 🌸

okay this is the important part, pay attention bestie, i'm gonna need you to lock in 🔒

• The vector versions of the math functions operate component-wise. The description is per-component. so every lane does its own lil thing, independently, main character energy in each slot. ✨
• The built-in math functions are not affected by the prevailing rounding mode in the calling environment, and always return the same value as they would if called with the round to nearest even rounding mode. like, she does not care what your environment is going through, she's stable, she's consistent, she's that girl. 💅
• The built-in math functions take scalar or vector arguments. For any specific use of these functions, the actual type has to be the same for all arguments and the return type unless otherwise specified. no mixing, no chaos, we match here. 🫶
• The generic type name gentype is used to indicate that the function can take float, float2, float3, float4, float8, float16, double, double2, double3, double4, double8, or double16 as the type for the arguments. pick your fighter. 🥊
• If extended with cl_khr_fp16(3clc), generic type name gentype may indicate half and half{2|3|4|8|16} as arguments and return values. half precision has entered the chat 🌈
• The generic type name gentypef is used to indicate that the function can take float, float2, float3, float4, float8, or float16 as the type for the arguments. float girlies only. 💗
• The generic type name gentyped is used to indicate that the function can take double, double2, double3, double4, double8, or double16 as the type for the arguments. double girlies only, precision princesses. 💜

and that's the whole page!! this manual page came from The Khronos Group, dated 01/14/2021, and it lives in section 3clc as FLOOR(3clc) — mwah, take care of her, she rounds down so you don't have to 💋✨
