💖 MIX(3clc) 💖

okay bestie, this is the OpenCL Manual page for mix, and it's genuinely one of the cutest little built-ins in the whole common functions lineup. no cap. let's get into it 🫶

---

✨ NAME ✨

mix — linear blend of x and y. it's giving "fade between two things" energy 💅

here's the whole squad of signatures, exactly as written, don't come for me:

gentype mix(gentype x, gentype y, gentype a);

gentypef mix(gentypef x, gentypef y, float a);

gentyped mix(gentyped x, gentyped y, double a);

gentype mix (gentype x, gentype y, half
a)      // if half extension enabled

---

🌸 DESCRIPTION 🌸

it returns the linear blend of x and y, and it's implemented like this, literally:

x + (y - x) * a

so like, a is the main character here — it's the vibe slider. a must be a value in the range 0.0 ... 1.0.

💀 and if a is not in the range 0.0 ... 1.0, the return values are undefined. not a warning, not a suggestion — undefined. don't do it, bestie, i'm begging 🙈

🎀 NOTES 🎀

okay this part is the iykyk section, so pay attention:

• 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. she's versatile ✨
• 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.
• the built-in common functions are implemented using the round to nearest even rounding mode. rounding is lowkey iconic in its own way 🌈
• 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 cute, so smol 🧚
• the mix function can be implemented using contractions such as mad(3clc) or fma(3clc). slay, optimized 💅
