Name
length - return scalar Euclidean length of a vector
Synopsis
float length(float v); float length(float1 v); float length(float2 v); float length(float3 v); float length(float4 v); half length(half v); half length(half1 v); half length(half2 v); half length(half3 v); half length(half4 v); fixed length(fixed v); fixed length(fixed1 v); fixed length(fixed2 v); fixed length(fixed3 v); fixed length(fixed4 v);Parameters
- v
- Vector of which to determine the length.
Description
Returns the Euclidean length of a vector.
Reference Implementation
length for a float3 vector could be implemented like this.
float length(float3 v) { return sqrt(dot(v,v)); }Profile Support
length is supported in all profiles.
Support in the fp20 is limited.
