NAME
normalize − Normal vector length 1.
floatn normalize(floatn p);doublen normalize(doublen p);DESCRIPTION
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.
