Fractions of Runes

[quote=CrysJaL]I've been looking at Runes recently with regards to abilities and I've noticed some abilities require X amount of Ap such as with [[Sona]]'s abilities [icon=aria of perseverance] and [icon=song of celerity] (Often say 100 Ap) for increased effectiveness in some way. Now my question relates to runes which provide bonuses that go into decimals such as 4.95 Ap quints and the like. My question is whether this stat would be rounded up for effect in the AP. Would an effective 99.95 Ap round up to the 100 Ap required to boost the abilities power? Thanks community, you're so helpful with these nooby questions :)[/quote]

[quote=FantasySniper]If it says the ratio is "per 100", then it is just a simpler way of saying minimal percentages. The 2% AP scaling applies even if you don't have 100 AP. When it comes down to decimal values for scaling, I honestly have no idea if it rounds it or simply uses the number as is.[/quote]

[quote=Lugignaf][quote=FantasySniper] When it comes down to decimal values for scaling, I honestly have no idea if it rounds it or simply uses the number as is.[/quote] It rounds visually, but it uses the exact number for damage/scaling calculations. For example, say you have 499.4 AP, it'll visually round it to 499, but all numbers that scale off your AP will actually do damage as if you had 499.4 AP. Bumping it to 499.5 or higher will do the same, except it will visually show 500.[/quote]
