S “RandSeed” Command

• You can specify an integer from 0 to 9 for the argument of this command. 0 specifies non-

sequential random number generation. An integer from 1 to 9 uses the specified value as
a seed for specification of sequential random numbers. The initial default argument for this
command is 0.

• The numbers generated by the ClassPad immediately after you specify sequential random

number generation always follow the same random pattern.

Problem

Use this keyboard:

Operation

mth

abc

cat

2D

Generate sequential random
numbers using 3 as the
seed value.

Cmd

[RandSeed] 3 U

Generate the first value.
Generate the second value.
Generate the third value.

Func

[rand]

U

[rand] U
[rand] U

Tip

• Random values generated by these commands are pseudo random values.

• The arguments a and b of “rand(a,b)” and “randList(n,a,b)” must be integers, subject to the

following conditions.

a < b

µ

E

10

b – a < 1

E

10

I Integer Functions

These functions take integers only as their arguments and return integers.

S “iGcd” Function

Syntax: iGcd(Exp-1, Exp-2[, Exp-3…Exp-10)]

(Exp-1 through Exp-10 all are integers.)

iGcd(List-1, List-2[, List-3…List-10)]

(All elements of List-1 through List-10 are integers.)

Function:

• The first syntax above returns the greatest common divisor for two to ten integers.
• The second syntax returns, in list format, the greatest common divisor (GCD) for each of

the elements in two to ten lists. When the arguments are {a,b}, {c,d}, for example, a list will
be returned showing the GCD for a and c, and for b and d.

Description:

• All of the lists must have the same number of elements.
• When using the “iGcd(List-1, List-2[, List-3…List-10)]” syntax, one (and only one)

expression (Exp) can be include as an argument in place of a list.
