all numeric values input or output are enforced by the compiler to have documented units. Code is clear and simple, like this:
length x = 1000.0 * meter; velocty v = 2.0 * nautical_mile / hour; ... time t = x / v; // typically LOTS of computations here ... cout << "Time in seconds = " << t / second;
I like this notation. I'm not sure, however, why t = x / v should involve lots of computation. If length, velocity, time are implemented as I proposed in my other email, x would contain the length in meters, v the velocity in meters per second, and time the time in seconds. Thus, one division. The conversions into SI units would be done in the assignments above.
