In what order are these boosts applied when calculating damage?

Question

Scenario- a Vanilluxe holding an ice gem uses ice beam on a Gliscor and lands a critical hit. In what order will the damage be calculated?

Ex-
1) ice gem

2) critical hit

3) STAB

4) super effectiveness

I randomly put this down. please tell me what order it really is.

Answer 1

It doesn't matter how you calculate it really. All the numbers get multiplied so it's the same.

Example:
90 x 1.5 x 1.5 x 2 x 4 = 1620
90 x 2 x 4 x 1.5 x 1.5 = 1620

Answer 2

The multiplication order does matter, because the game usually rounds the numbers at every step instead of using decimals or floating point numbers. Ice gems are a power modifier, which means it's applied directly to ice beam's 95 base power. After the game calculates a damage number with the power, the Pokemon's attack and defense stats, and Vanilluxe's level, it applies the critical hit, STAB, and type effectiveness in that order. So your random order turned out to be correct.

Probably worth making clear this is extremely academic, to the point "it makes no difference" would still be a good summary of what's happening
