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 (sequential
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.
