normalize3clc

floatn normalize(floatn p);

doublen normalize(doublen p);

Overview

Returns a vector in the same direction as p but with a length of 1.

Notes

Built-in geometric functions operate component-wise. The description is per-component. floatn is float, float2, float3, or float4 and doublen is double, double2, double3, or double4. The built-in geometric functions are implemented using the round to nearest even rounding mode.

The geometric functions can be implemented using contractions such as mad(3clc) or fma(3clc).

If extended with cl_khr_fp16(3clc), generic type name gentype may indicate half and half{2|3|4} as arguments and return values.
