Rounding of .5 - Reference: 1/8/2017 01:36:30

Values ending in .5 aren't always rounded the same way. Sometimes they round down, sometimes they round up. I tested a few cards/settings and came up with the following:

Sanctions Card: Sanction amount rounds down.
50% sanction on 5 income leaves the player with 3 income.

Reinforcement Card (value set to a percentage times # of turns passed): Rounds Down
Numbers ending in .5 round down, with one exception. Anything less than 1 army will round up (you don't get a reinforcement card of +0). For example, 50% per turn times 5 turns = 2.5, which rounds down to +2 armies.

3.5 * 3 armies = 10.5, which rounds down to 10. This is why blockade cards are set to 351% in strategic games.

Bomb Card (halves armies on affected territory): Rounds down
Bombing 5 armies leaves 2 remaining (50% * 5 = 2.5, which rounds down).

Kill rates (offensive and defensive): Rounds up
These round up from .5. For example, with 5 defenders and 70% defensive kill rate, you will kill 4 attackers (5*.7 = 3.5, rounds up to 4). For the standard offensive kill rate, this is never an issue, but it works the same if it is modified to 70%.

Attack by percentage: Rounds down.
50% with 5 available attackers will move 2 armies. 50% * 5 = 2.5, rounds down to 2.

If you can think of others add them below and I'll update this post.

nobody will ever understand the enigma that is Fizzer's thinking process

It's probably not the thinking process, just how these cards are programmed/how the data is stored/which values are actually rounded (e.g., the amount of troops remaining or the amount of troops lost).

So that's why...! I'd include this information in your Attack By Percent knowledge bomb.

Once again, thank you so much for the share!

Yeah I reckon knyte is right, like sanction cards, for a 5 income, 50% sanction, income=5*0.5=2.5 rounds up to 3. Maybe just depends on which value is being rounded in fizzers code.

i thought the same thing at first too

as in you could round two parts of the variable - either the number itself or the amount taken away from a number

but then... why would reinforcement cards round down? o_O

If, for example, you wanted to set the card so that you get 1 reinforcement for every two territories, it would be odd if you got 2 for having three territories. Really any decimal should round down to follow that rule correctly. Did you check the rounding with decimals above .5 jz?

Edit: clarification
