I'm going to be using this float to default-initialize a construction
parameter. For example:
struct default_alpha
{
    static const float value = 1.0f;
};
class foo
{
     foo( float r, float g, float b, float a = default_alpha::value );
};
You can use constant in namespace scope:

namespace default_alpha
{
    static const float value = 1.0f;
}
