damage calculation using calculator

So there are two different calculators, one is to enter attribute, another is target armor. So suppose I have a result of 29.9 damage from calculator 1, should I just round it off to 29 damage as an input for the 2nd calculator, or should I eneter 29.9? So if you get the final value, would you round it off before you add the 20% from customized weapons?

This is a very important question becasue if damage is rounded off in each step, +14% and +15% weapon doesn't make a difference but if damage is rounded off in the final value it would make a 1 difference.

You keep the exact values throughout the whole thing and round off the final result. 29.9 Damage, if the final result should be 30.

29.9 rounds to 30, not 29. It just depends on how accurate you want your answer to be. I usually don't round until the very end, and when you do, round correctly.

When I use a +14% weapon and +15% weapon on a low level monster, the result turns out to be the same (97 damage) , so I thought 14 and 15% didn't make any difference becasue the damage was not over 100 so it didn't give a 1 damage difference becasue 0.9 rounded off to 0 instead of rounding off to 1.

If you are true that 0.9 is rounded off to 1 and damage is rounded off in the final stage, In my case the damage made no difference becasue it might be 96.5 and 97.4 . That means 14% and 15% could make when damage is below 100 e.g. when the damage is 44.4 -->44 and 44.6--->45 , am I right?
