min

> # 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.
