[Boost-users] How to add a type to is_arithmetic

Hi,

Suppose I define a class fixed_point as

class fixed_point{
....some operations are defined here

private:
int _integer_part;
unsigned _fractional_part
}

I want is_arithmetic<fixed_point>::type to be true_

Of cause, I can partially specialize the template class as

template <>
struct is_arithmetic<fixed_point> {
... blah blah
};

If I use the above approach, shall I put it into the namespace boost or not?

Also, I'm wondering if there is any generic way to do this?

Thanks,
Peng
