/*
The Math.random() function returns a floating-point, pseudo-random
number in the range 0 to less than 1 (inclusive of 0, but not 1)
with approximately uniform distribution over that range — which you
can then scale to your desired range. The implementation selects the
initial seed to the random number generation algorithm; it cannot
be chosen or reset by the user.
