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.
