Notes:
• With each rand execution, the TI-84 Plus CE generates the same random-number
sequence for a given seed value. The TI-84 Plus CE factory-set seed value for rand
is 0. To generate a different random-number sequence, store any nonzero seed
value to rand. To restore the factory-set seed value, store 0 to rand, or reset the
defaults by going to y L 7:Reset....
• The seed value also affects randInt(, randNorm(, and randBin( instructions.
