1 RND numeric expression
R N D is a numeric function wh ich generates random numbers. If the value of the argument is less than one but greater than or equal
to zero, the random number is less than one and greater than or equal to zero. If the argument is an integer greater than or equal
to 1, the result is a random number greater than or equal to 1 and less than or equal to the argument. If the argument is greater
than 1 and not an integer, the result is a random number greater than or equal to 1 and less than or equal to the smallest integer
which is larger than the argument:

The same sequence of random numbers is normally generated because the same "seed" is used each time the PC-3 Pocket Com-
puter is turned on. To randomize the seed, see the RANDOM verb.
