Name
min - returns the minimum of two scalars or each respective component of two vectors
Synopsis
float min(float a, float b); float1 min(float1 a, float1 b); float2 min(float2 a, float2 b); float3 min(float3 a, float3 b); float4 min(float4 a, float4 b); half min(half a, half b); half1 min(half1 a, half1 b); half2 min(half2 a, half2 b); half3 min(half3 a, half3 b); half4 min(half4 a, half4 b); fixed min(fixed a, fixed b); fixed1 min(fixed1 a, fixed1 b); fixed2 min(fixed2 a, fixed2 b); fixed3 min(fixed3 a, fixed3 b); fixed4 min(fixed4 a, fixed4 b);Parameters
- a
- Scalar or vector.
- b
- Scalar or vector.
Description
Returns the minimum of two same-typed scalars a and b or the respective components of two same-typed vectors a and b. The result is a three-component vector.
Reference Implementation
min for float3 vectors could be implemented this way:
float3 min(float3 a, float3 b) { return float3(a.x < b.x ? a.x : b.x, a.y < b.y ? a.y : b.y, a.z < b.z ? a.z : b.z); }Profile Support
min is supported in all profiles. min is implemented as a compiler built-in.
Support in the fp20 is limited.
