For abilities in League of Legends, does extra damage on abilities (AD and AP Scaling) round down to the number shown on the ability tool tip? Or does it stay at the actual number. I'm especially curious for percentage health skills.
According to this thread from 2009, damage is calculated with the most precise numbers possible.
For example: suppose I'm a Level 1 Annie with no items, runes or masteries. I'm at
263/460 HP right now, and I have
30 MR. Elise has no MPen and she throws a Level 1 Neurotoxin, which deals
40 + 8% current HP, at me. The raw damage would be
40 + 0.08 * 263 = 61.04. After MR, it deals
61.04 * 100 / (100 + 30) = 46.95(...) damage to me. I take that amount of damage, leaving me at
216.05 HP. This will be displayed as
So, in short, it stays at the actual number, then when all calculations are complete and the final damage amount is determined, that number is subtracted from the current HP of the victim. Health will be rounded on the display, though it appears that so long as you have more than
0 HP (even at
0.01 HP), the display will show
