Units have 20hp but only display 10

[prestidigitation]

I've wondered about this one for awhile and finally found a good picture showing it. The unit is at 10 displayed strength, but is giving off 19 rather than 20 supply. This implies both that it has lost .5 hp and that the game tracks 20 actual HP (or 10hp in 0.5 increments). Therefore a 0+ attack isn't predicting 0 damage with a chance of 1, but 0.5 damage.

I wonder if this is two different rounding calculations at play. That is, the ship is actually partially damaged but still rounds up to strength 10. However, whatever small amount of damage it has sustained caused its available supply to round down to 19. Or maybe I am misunderstanding your question. What I believe you are asking is why a 10 strength supply ship would provide only 19 supply?

[cutydt02]

yes, about 0.5 dmg taken or slighly less, but the game will round up to 10 anyway. That means sometimes the dmg calculator showing that 0 dmg caused/taken doesn't mean they do nothing.

IMO they probably have something like 50HP or 100HP (following the OP's reasoning).

Or maybe the HP is internally a fractional number (floating-point type) instead of an integer.

Does the number 19 remain yellow the following turns ?

PS : here is a lived example in computer programming :

1.3 + 1.3 = 2.6

If you round each number for the display, you get:

1 + 1 = 3

Was the Supply Ship attacked recently? Perhaps it still has some suppression (efficiency degradation) even though it has full health?

Yes, it’d been like that for several turns.

No suppression, afaik ships can’t be suppressed. It was strafed by a fighter

Also a possibility, and probably the truth in terms of implementation, but IMO it’s easiest to think of it as 20hp.
