✨ STEP(3clc) ✨

okay bestie, welcome to the step page from the OpenCL Manual 💖 it's short, it's sweet, it's literally one tiny function and honestly? iconic.

---

🌸 NAME 🌸

step — returns 0.0 if x < edge, else 1.0.

like. that's the whole job. that's the gig. 🫶

here's how you call her:

gentype step(gentype edge, gentype x);

gentypef step(float edge, gentypef x);

gentyped step(double edge, gentyped x);

gentype step (half edge, gentype x)
// if half extension enabled

---

🦋 DESCRIPTION 🦋

Returns 0.0 if x < edge, else 1.0. 💅

that's it. no drama. x is smaller than edge? you get 0.0. otherwise? 1.0. periodt.

🎀 NOTES 🎀

okay so there's some generic type name lore you need to know, don't skip this part bestie:

• 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. ✨
• the generic type name gentypef means the function can take float, float2, float3, float4, float8, or float16 as the type for the arguments. 🌈
• the generic type name gentyped means 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. no cap, that's just how it is. 👑
• if extended with cl_khr_fp16(3clc), the generic type name gentype may indicate half and half{2|3|4|8|16} as arguments and return values. 🧚
