kRandom Number Generation (RAND)uRandom Number Generation (0 to 1) (Ran#, RanList#)

Ran# and RanList# generate 10 digit random numbers randomly or sequentially from 0 to 1. Ran# returns a single random number, while RanList# returns multiple random numbers in list form. The following shows the syntaxes of Ran# and RanList#.

Ran# [a]

1

< a < 9

RanList# (n [,a])

1

< n < 999

•n is the number of trials. RanList# generates the number of random numbers that corresponds to n and displays them on the ListAns screen. A value must be input for n.

•“a” is the randomization sequence. Random numbers are returned if nothing is input for “a”. Entering an integer of 1 through 9 for a will return the corresponding sequential random number.

•Executing the function Ran# 0 initializes the sequences of both Ran# and RanList#. The sequence also is initialized when a sequential random number is generated with a different sequence of the previous execution using Ran# or RanList#, or when generating a random number.
