===In Pokémon GO===
the [[Pokémon GO]], the type effectiveness chart differs from the equivalent type chart in contemporaneous core series games. Moves that are ineffective in the core series deal 0.51× damage instead (0.8× prior to June 21, 2017), not very effective moves deal 0. 714× damage (0.8× prior to June 21, 2017), and super effective moves deal 1.4× damage (1.25× prior to June 21, 2017). If the defending Pokémon is dual-typed, the modifier is calculated as the product of the modifiers for both of its types.
