RPG Damage Dice to Expected Value Converter
About RPG Dice Notation
Dice notation like "2d6+3" means "roll two 6-sided dice and add 3 to the total".
- d = die/dice
- number before d = how many dice to roll
- number after d = number of sides on each die
- +/-X = optional modifier added or subtracted from the roll
The expected value is calculated as:
E = (numDice * (1 + sides) / 2) + modifier
