RADIANS(3clc)

💫 RADIANS(3clc) 💫

okay bestie, sit down, because we're doing RADIANS today — straight out of the OpenCL Manual, no cap. it's giving trigonometry but make it GPU. ✨

---

🌈 NAME 🌈

radians — converts degrees to radians. that's it. that's the whole job. 💅

gentype radians(gentype degrees);

---

🦋 DESCRIPTION 🦋

she takes your degrees and turns them into radians, literally:

(pi / 180) * degrees

that's the vibe. degree in, radian out, slay. 🔥

🎀 NOTES 🎀

okay so about gentype — it's a generic type name, which is just fancy speak for "this function is flexible and accepts a whole squad of types". the generic type name gentype means the function can take float, float2, float3, float4, float8, float16, double, double2, double3, double4, double8, or double16 as the type for the arguments. yes, all twelve. she's versatile like that. 👑

the generic type name gentypef means the function can take float, float2, float3, float4, float8, or float16 as the type for the arguments. (the f is for float, iykyk 🍓)

the generic type name gentyped means the function can take double, double2, double3, double4, double8, or double16 as the type for the arguments. (the d is for double, she's bougie 💜)

lowkey important: the built-in common functions are implemented using the round to nearest even rounding mode. remember that bestie, it comes up.

and if it's extended with cl_khr_fp16(3clc), the generic type name gentype also includes half and half{2|3|4|8|16}. tiny floats, iconic behaviour. 🧚
