Function Calculations
u “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 Cmd [RandSeed] 3 w
numbers using 3 as the
seed value.
Generate the first value. Func [rand] w
Generate the second value. [rand] w
Generate the third value. [rand] w
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
a , b < 1E10
b – a < 1E10
