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;
ARANDINT(1,6); C9855+A;
BRANDINT(1,6); D9855+B;
RETURN {A+B/100, CHAR(C), CHAR(D)};
END;

Have fun and roll those dice,

Eddie
