Random Number Generator
Pressing ´# (random number) will generate a random number
(part of a uniformly distributed pseudo-random number sequence) in the
range 0 r <1.

number sequence. Any time you generate a random number, that number
becomes the seed for the next random number. You can initiate a different
random number sequence by storing a new seed for the random number
generator. (Repetition of a random number seed will produce repetition of
the random number sequence.)
