If I want to "just use" random numbers in a simple program, I don't want to see the same values every time. If I want to repeat the values every time, I'll take the time to seed it so that happens. > 4. While we're at it, should uniform(a, b) generate by default something > in [a, b] or [a, b)? [a,b) Every other piece of range-like code is zero based, and excludes the upper bound. This should be no different. It makes the code simpler too. -Steve
