k 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.
