Random Number Generation (RAND)
Random 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]
RanList# (n [,a])
n
• is the number of trials. RanList# generates the number of random numbers that
n
corresponds to and displays them on the ListAns screen. A value must be input for
a
• " " is the randomization sequence. Random numbers are returned if nothing is input for "
Entering an integer of 1 through 9 for
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.
