    /*  Clamp value to 0..kOOMaxCredits.
        The important bit here is that kOOMaxCredits can't be represented
        exactly as a double, and casting it rounds it up; casting this value
        back to an OOCreditsQuantity truncates it. Comparing value directly to
        kOOMaxCredits promotes kOOMaxCredits to a double, giving us this
        problem.
        nextafter(kOOMaxCredits, -1) gives us the highest non-truncated
        credits value that's representable as a double (namely,
        18 446 744 073 709 549 568 decicredits, or 2047 less than kOOMaxCredits).
