    // Create a double channel with range [-0.5 .. 0.5]
    struct double_minus_half  { static double apply() { return -0.5; } };
    struct double_plus_half   { static double apply() { return  0.5; } };
    typedef scoped_channel_value<double, double_minus_half, double_plus_half> bits64custom_t;

    // channel_convert its maximum should map to the maximum
    bits64custom_t x = channel_traits<bits64custom_t>::max_value();
    assert(x == 0.5);
    bits16 y = channel_convert<bits16>(x);
    assert(y == 65535);
