ROOTN(3clc)

👑 NAME 👑

rootn — bestie, this one computes x to the power 1/y. That's it. That's the whole job. 💖

floatn rootn(floatn x, intn y);

float rootn(float x, int y);

doublen rootn(doublen x, intn y);

double rootn(double x, int y);

halfn rootn(halfn x, intn y);

half rootn(half x, int y);

✨ DESCRIPTION ✨

Compute x to the power 1/y. periodt. 🎀

🌸 NOTES 🌸

okay so here's the lore you actually need, bestie:

• The vector versions of the math functions operate component-wise. The description is per-component. 🧚
• 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 like, rounding mode? she doesn't know her. 💅
• The built-in math functions take scalar or vector arguments. For any specific use of these function, the actual type has to be the same for all arguments and the return type unless otherwise specified. no mixing, no chaos, we stay consistent. 👑
• 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.
