💖 ACOS(3clc) — OpenCL Manual 💖

okay bestie, welcome to the OpenCL manual page for ACOS(3clc) 🌸 yes the page is called ACOS but the actual ✨ content ✨ is about the error functions, we love a little mystery, it's giving plot twist 🎀

---

🌈 NAME 🌈

erf, erfc — error functions, periodt 💅

gentype erf(gentype );

gentype erfc(gentype );

---

🦋 DESCRIPTION 🦋

erf is the error function — the one you run into when you're integrating the normal distribution. iconic behaviour honestly 🧚

erfc is the complementary error function. no cap, that's the whole description, she's short and sweet 🍓

✨ NOTES ✨

okay so here's the tea, listen up 🫶

• the vector versions of the math functions operate component-wise. the description is per-component. so like, each lane does its own thing 💫
• 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. consistent queen 👑
• 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 ⭐
• 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 💜
• 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 💖
