Rounding the numbers for powers

[MaskedRoninTTV]

Some numbers for powers aren't rounded as they should be.
For instance Incan Craig U40 should deal 114 to leader because it's 113.8 by calculations.
Another example is Lightning Bolt level 4, should do 57 to leader.

RedLynx rounds down numbers that end with 5 but the rest is still rounded up.
So 9.6-10.5 would all be rounded to 10 while 10.6 is rounded up to 11.

We do all our rounding in the converter tool iirc so ill tag this as api but if we do rounding somewhere else as well, please add the relevant tags (whoevers working on this).
