💖 TGAMMA 💖

okay bestie, so this is a page from the OpenCL Manual, and it's literally all about tgamma. it's giving math-girlie main character energy and we are obsessed. 💅

---

✨ NAME ✨

tgamma — the Gamma function. yeah that's it, that's the vibe.

gentype tgamma(gentype );

---

🌸 DESCRIPTION 🌸

tgamma computes the gamma. fr fr. that's the whole description. iconic of it honestly. 👑

---

🦋 NOTES 🦋

okay so here's the tea, and there's a lot of it, so buckle up:

• the vector versions of the math functions operate component-wise. the description is per-component. no cap.
• 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. so whatever your environment thinks it's doing, bestie is unbothered. ✨
• 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.

not me listing every single one of those types 💀 but that's literally what it says so we're keeping all of them, periodt.

and that's the whole page, bestie! 💖✨🦋

cute lil sign-off: this lil legend was brought to you by The Khronos Group, dated 01/14/2021, and the page was literally called TGAMMA(3clc). slay. 💅🌸
