k Random Number Generator (rand, randList, RandSeed)
• The ClassPad random number generator can generate truly random numbers (non-
sequential random numbers) and random numbers that follow a particular pattern (sequen-
tial random numbers). Using the "randList" function, you can generate a list whose
elements contain random numbers. There are nine different patterns for generation of
sequential random numbers. Use the "RandSeed" command to switch between non-
sequential and sequential random number generation, and to select the sequential random
number generation pattern.
u ClassPad Operation
(1) Use the "RandSeed" command to configure random number generation settings, if
required.
(2) Use the "rand" function or "randList" function to generate the random numbers.
