Pokemon Type Calculator

This tool reads the eighteen type chart both ways. Give it a single or dual typing and it sorts all eighteen attacking types into what hits for four times, double, half, a quarter or nothing at all; give it a move type and a defender instead and it returns the exact multiplier for that one hit. A dual type is simply the product of its two columns, which is where the 4x and 0.25x results come from. The chart used is the Generation 6 one, unchanged since Fairy was added in X and Y. Abilities such as Levitate and moves with their own typing rules sit outside the chart and are not applied.
