NAME

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

SYNOPSIS

   float  degrees(float  a);
   float1 degrees(float1 a);
   float2 degrees(float2 a);
   float3 degrees(float3 a);
   float4 degrees(float4 a);
 
 
 

   half   degrees(half  a);
   half1  degrees(half1 a);
   half2  degrees(half2 a);
   half3  degrees(half3 a);
   half4  degrees(half4 a);
 
 
 

   fixed  degrees(fixed  a);
   fixed1 degrees(fixed1 a);
   fixed2 degrees(fixed2 a);
   fixed3 degrees(fixed3 a);
   fixed4 degrees(fixed4 a);

PARAMETERS


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

DESCRIPTION

Returns the scalar or vector converted from radians to degrees.

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

REFERENCE IMPLEMENTATION

degrees for a float scalar could be implemented like this. 
   float degrees(float a)
   {
     return 57.29577951 * a;
   }

PROFILE SUPPORT

degrees is supported in all profiles except fp20.
