The rand() function always returns a value between 0 and 1. Specifying a 
different seed will just give a different sequence of random numbers.
Most computer random number generators are actually pseudo-random. They 
produce a specific sequence of numbers from each seed value. If you use 
seed(444), you will get a different sequence from what you would get if 
you used seed(999), and that sequence will always be the same.
