FAST_DISTANCE(3clc)

✨ FAST_DISTANCE ✨

okay bestie, welcome to the OpenCL Manual page for fast_distance 💖 this one lives in the 3clc section and it is so chill, you're gonna love it

---

🎀 NAME 🎀

fast_distance — vector distance 🦋

float fast_distance(floatn p0, floatn p1);

---

🌸 DESCRIPTION 🌸

bestie it literally returns fast_length(3clc)(p0 - p1). that's it. that's the whole vibe. no cap. ✨

---

💅 NOTES 💅

okay so the built-in geometric functions do their thing component-wise — like, the description is per-component, one at a time, very main character energy 👑

and real quick, floatn means float, float2, float3, or float4, and doublen means double, double2, double3, or double4. memorise it, iykyk 🧚

also the built-in geometric functions are implemented using the round to nearest even rounding mode. periodt.

the geometric functions can be implemented using contractions such as mad(3clc) or fma(3clc) 🫶
