Generating random numbers


Hello,
Turn calculator ON, press MENU if you see no icons. Use arrow key to highlight the RUN application. Press OPTN, press F6 to pan right. Press F3: Prob, then F4:Ran# then EXE to execute.

Each time you press EXE a new random number is generated. You might want to fix the number of decimal digits to less than the 10 digits displayed by default.

By default number generated are between 0 and 1. If you want numbers between 0 and 100 you enter Ran#(100).

Hope it helps.
