Dice Notation

Dice notation is fully understood by pydice.

Dice

Die rolls are given in the form AdX. A (amount) and X (sides) are variables, separated by the letter "d", which stands for die or dice.

• A is the number of dice to be rolled (usually omitted if 1).
• X is the number of faces of each die.

If the final number is omitted, it is typically assumed to be a six, but in some contexts, other defaults are used.

For example, if a game would call for a roll of d4 or 1d4 this would mean, "roll one 4-sided die." 3d6 would mean, "roll three six-sided dice"

See Wikipedia for a complete definition.

Patterns

AdX notations can be integrated in complex expressions: the resulting scores will then behave like integers.

Any mathematical expression is allowed:

>> 1d10+1d5+1
>> 1d20-6
>> 1d6*2
>> 2d20//4
>> 1d6*(1d4**2)

...Etc

Builtin python functions

Currently, the following python functions are allowed: abs, max, min
