Negative percentage if ship shields are set to 0 in ship template about emptyepsilon

[daid]

It caused a division by zero, which resulted in a NaN, which in turn was converted to a MIN_INT value.

Should be fixed now with the patch I pushed.

Think you missed one part on src/screens/crew6/engineeringScreen.cpp. The rear shield is still displaying -2147483648% on the Engineering screen.

Line 98:

shields_display->setValue(string(my_spaceship->getFrontShieldPercentage()) + "% " + string(int(100 * my_spaceship->rear_shield / my_spaceship->rear_shield_max)) + "%");

Should be

shields_display->setValue(string(my_spaceship->getFrontShieldPercentage()) + "% " + string(my_spaceship->getRearShieldPercentage()) + "%");
