MIN(3clc)

💖 MIN — bestie edition 💖

okay so this is min from the OpenCL Manual, and she is min(3clc) if you're being formal about it. pull up a chair, we're finding the lesser of two values and we're doing it adorably. 🎀

---

✨ NAME ✨

min — returns the lesser of two values. literally just vibes-based comparison, no cap. 🦋

---

🌸 SYNOPSIS 🌸

bestie the signatures are giving versatile. here they are, verbatim, don't touch:

gentype min(gentype x, gentype y);

gentypef min(gentypef x, float y);

gentyped min(gentyped x, double y);

gentype min (gentype x, half y)      //
if half extension enabled

yes that last one has the comment in the signature. iconic. 💅

---

💜 DESCRIPTION 💜

okay so min returns y if y < x, otherwise it returns x. that's the whole thing. that's the tea. ☕

🚨 MAJOR WARNING 🚨 if x and y are infinite or NaN, the return values are undefined. not "kinda weird", not "close enough" — undefined. don't come crying to me. 😭

🎀 NOTES 🎀

• 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. so many options, she's flexible, we love that. ✨
• 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 girlies only. 💖
• 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 precision divas, this one's for you. 👑
• the built-in common functions are implemented using the round to nearest even rounding mode. that's the rules, babe. no arguing. 🌈
• 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. so like, half the size, double the drama. 🧚
