Let Em’ Roll

One way to simulate a pair of dice being thrown is to generate two random integers between 1 through 6.  The integers are either shown as a pair or vector of integers.  For calculators that do not have a list capacity or want a more compact representation, the program for the HP 32S II (which can easily apply almost to any other programming calculator), in the format A.0B, where A is one die and B is the other.   For example, 3.06 represents a 3 and a 6 being thrown.

The formula would be:   RandInt(1,6) + RandInt(1,6)/100

On certain Sharp calculators, such as the Sharp EL-W516T, the R.DICE function generates a single digit between 1 and 6.

HP Prime:  Graphical Representation of Dice

We can also use the Unicode representation of dice.

Unicode Character	Decimal	Hexadecimal
⚀	9856	2680
⚁	9857	2681
⚂	9858	2682
⚃	9859	2683
⚄	9860	2684
⚅	9861	2685

Unicode characters need to be in strings.  The HP Prime program RDICE returns a list, the roll in compact format, along with the Unicode representation.  This is only one of many ways to do it.

An example output of RDICE is {4.02, “⚃”, “⚁”}

HP Prime Program: RDICE

EXPORT RDICE()

BEGIN

// rolling dice A.0B

LOCAL A, B, C, D;

A≔RANDINT(1,6); C≔9855+A;

B≔RANDINT(1,6); D≔9855+B;

RETURN {A+B/100, CHAR(C), CHAR(D)};

END;

Have fun and roll those dice,
