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 );
};
I'm not 100% sure if the above is legal C++. I haven't gotten to the point to where I could test it. I suppose I could try it with integrals, but I just haven't gotten around to it.
In .h header:Robert Dailey wrote:Is there a way I can define constant floats within class scope like you can with integral values? I was hoping boost could help in this area. For example:
struct default_alpha
{
static const float value = 1.0f;
};
The above is not legal, of course. Anyone? Thanks.
struct default_alpha { static const float value; };In .cc source file:
const float default_alpha::value = 1.0f;Is this answer too simple?
