ASIN(3clc)

✨ asin, _asinh, _asinpi — the sine functions 💖

okay bestie, welcome to the 3clc OpenCL manual page, this one is all about asin, _asinh, _asinpi — three lil trig cuties that live in the OpenCL math family 🎀. Let's get into it, no cap.

🌸 NAME 🌸

asin, _asinh, _asinpi — Sine functions.

gentype asin(gentype );

gentype asinh(gentype );

gentype asinpi(gentype x);

🦋 DESCRIPTION 🦋

• asin — this is the arc sine function, bestie. It's giving "give me the angle" energy 🌈.
• asinh — this is the inverse hyperbolic sine function. Hyperbolic, but make it inverse 💅.
• asinpi — this one computes asin (x) / π. Yes, it divides by pi, it's built different 🥧.

👑 NOTES 👑

okay so there's some important lore here, don't skip it 🙈

• The vector versions of the math functions operate component-wise. The description is per-component. So like, each lil lane does its own thing, independently, slay ✨.
• The built-in math functions are not affected by the prevailing rounding mode in the calling environment, and they always return the same value as they would if called with the round to nearest even rounding mode. Periodt, that's the vibe 🔥.
• 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, bestie, it's a matching-set situation 💀.
• 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. That's a whole roster 👑.
• If extended with cl_khr_fp16(3clc), the generic type name gentype may indicate half and half{2|3|4|8|16} as arguments and return values. Extra credit 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. Float-only club 💜.
• 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-only club, the precision girlies 🍓.

lowkey obsessed with how short this one is, we love a quick read 💅

and that's the whole page, bestie!! brought to you by The Khronos Group, dated 01/14/2021, and living in the OpenCL Manual — mwah, go call asin on something and thrive ✨🦋💖
