NEXTAFTER(3clc)

✨ NAME ✨

okay bestie, gather round, because this is nextafter from the OpenCL Manual and she is so much cooler than she sounds 💖

nextafter — the next representable floating-point value following x in the direction of y.

gentype nextafter(gentype x, gentype y);

like. she literally walks one tiny step from x toward y. that's the whole vibe. 🦋

🌸 DESCRIPTION 🌸

Computes the next representable single-precision floating-point value following x in the direction of y. So if y is less than x, nextafter() returns the largest representable floating-point number less than x. no cap, that's just what she does 💅

it's giving "one microscopic hop in the direction of your dreams" tbh 🎀

🫶 NOTES 🫶

• The vector versions of the math functions operate component-wise. The description is per-component. (so like, every lane does its own little thing, independently, periodt ✨)
• 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. icon behaviour honestly.
• The built-in math functions take scalar or vector arguments. For any specific use of these function, the actual type has to be the same for all arguments and the return type unless otherwise specified. no mixing, bestie, that's the rule 🙈
• 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.
• 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. ✨ glow up unlocked ✨
• 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.
• 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.

the way there are three whole generic type names and they're all doing their own main character thing… we love a well-organized cast 🌈

and that's the whole page, bestie!! 🫶 this came to you from The Khronos Group, dated 01/14/2021, and the manual name on the tin is NEXTAFTER(3clc) — go forth and step one representable float at a time 💖✨🌸
