--- Comment #6 from Darin Adler <darin at apple.com> ---
I suggest we use this code that selects either double or long double based on the size of the integer.

    std::conditional<sizeof(m_value) <= 4, double, long double>::type result = rhs;
    result *= m_value;

Note the importance of converting rhs to long double *before* doing the multiplication. I’m grabbing this bug and will fix it.
