•To display numbers with three significant digits, set the display notation settings to “floating point”.

Random dice

To simulate a die roll, a random integer between 1 and 6 can be generated by pressing .1=. To generate further random numbers in succession, press =for each number. Press sto exit.

Random coin

To simulate a coin flip, 0 (heads) or 1 (tails) can be randomly generated by pressing .2=. To generate further random numbers in succession, press =for each number. Press sto exit.
