Random Number Generation (RAND)
u
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
] 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.
