radians

> # NAME

> radians - converts values of scalars and vectors from degrees to radians

> # SYNOPSIS

>       float  radians( float  a );
>       float1 radians( float1 a );
>       float2 radians( float2 a );
>       float3 radians( float3 a );
>       float4 radians( float4 a );

>       half   radians( half  a );
>       half1  radians( half1 a );
>       half2  radians( half2 a );
>       half3  radians( half3 a );
>       half4  radians( half4 a );

>       fixed  radians( fixed  a );
>       fixed1 radians( fixed1 a );
>       fixed2 radians( fixed2 a );
>       fixed3 radians( fixed3 a );
>       fixed4 radians( fixed4 a );

> # PARAMETERS

> a

>   Vector or scalar of which to convert from degrees to radians.

> # DESCRIPTION

> Returns the scalar or vector converted from degrees to radians.

> For vectors, the returned vector contains each element of the input vector converted from degrees to radians.

> # REFERENCE IMPLEMENTATION

> radians for a float scalar could be implemented like this.

>       float radians(float a)
>       {
>         return 0.017453292 * a;
>       }

> # PROFILE SUPPORT

> radians is supported in all profiles except fp20.
