Yamato right click does less damage with Split Shot active

[Grimbus]

Wanted to test out a Yamato Shotgun build, which is Express Shot + Split Shot. But there seems to be bugged interaction between Yamato's right click and Split Shot.

A full magazine without Split Shot active does 422 damage. Activating Split Shot reduces the damage to 421 damage.

Tried this same setup for Viscous, similar situation. His full right click mag will do 420 damage without Split Shot, but with Split Shot active it does just 419. A negligible difference, probably won't matter in any real games.

It's not a game bug, it's the damage rounding system. Due to the fact that damage is usually not an integer due to the weapon's percentage damage boost system.
When the damage from the weapon passes over the hero the game calculates the damage to a greater or lesser degree, by a simple system if >0.5 then +1, if <0.5 then +0.
Therefore, these rules apply:
Damage from alternative attack yamata 81,**
I'm too lazy to count so let's assume that the damage 81.40, 0.40 < 0.5, so add 0 to the attack, and leave 0.40 to the next attack
So the first attack = 81
Second attack is already 81.40+0.40=81.80, which is >0.5 so = 82.

Thus we get different damage
First 4 attacks = 421
Second 4 attacks = 422, since there is still damage left
The damage will fluctuate 421>>422>>421>>>422 etc.
