Description:

Mathematical calculation error in ACE3/addons/weather/functions/fnc_calculateAirDensity.sqf: the Saturation vapor pressure _pSat calculated in line 26 is in Millibar insted of Pascal(can also be seen in stated source for theory in comment on line 25). Since 1mbar = 1hPa = 100Pa, the pressure is of by a factor of 100. following in very inacurate air densities which in turn has a impact on things like mortar ballistic curves.

Steps to reproduce:

Read the code (ACE3/addons/weather/functions/fnc_calculateAirDensity.sqf) on line 26;
