(0.623) Hit but no damage, shown as 0 damage but does 1dmg

[Circuitbreaker]

Some River Pirates tend to challenge me for a ranged duel. During the unequal battle between my character armed with a crossbow and the enemy throwing stones at me, they actually manage to hit me sometimes and the game then usually shows "0 damage" as I'm all covered in heavy armor. If I look at my Hit Points however, I notice that 1 hit point is substracted from my total due to this "0 damage" hit.

Is damage shown on screen rounded down and actual damage inflicted rounded up ?

This is because your health and damage is in decimal form, but only an integer is displayed. Sometimes I get recieved 1 damage and I lose nothing from my HE display because you could say:

HE: 64.4 rounded to 64

Damage: 0.7 rounded to 1

but 64.4 - 0.7 is 63.7 rounded to 64.
