Forum:Is the weapon damage calculated

i know there is three bars that says DAMAGE, ACCURACY and FIRE RATE, but i dont know if the bonuses such as +159% Damage. is calculated or not,

Because i have a revolver called AX10 BLOODY REVOLVER, and it says that it does 848 in damage + 159%.

does it make 348 in damage +159%. or does it make 848+159%=2196?

and if it is calculated, are everything else also calculated???? plz answer me.
