100% ??

100% ??

((-3.00 - 0.00) / -3.00) * 100 = 100%

...?

((-3.00 - 0.00) / -3.00) * 100 = 100%

...?

So I see that as ((old - new) / old) * 100 = %. So if old is 50 and new is 75 : ((50 - 75) / 50) * 100 = -50%

How about ((new - old) / old) * 100 = %.

((0.00 - -3.00) / -3.00) * 100 = -100%

It's meant to be the |absolute value| of the difference between new and old in which case |-3.00 - 0.00| = 3 still yields -100% using your example.

Every time I see something go from negative to positive it's a positive increase, which is logically correct, but mathematically incorrect. So is it a decrease (-100%) as the formula would suggest? Imagine a graph with negative numbers above the line and positive below the line. The graph line would go down which makes sense if it's a -100% decrease.

Negatives and zero makes for interesting comparisons.

edit: removed a line I forgot to delete.

Everything you say is irrelevant, since reality breaks down at the operationalization of "rebelliousness" utilizing an interval variable, rather than a ratio. What does -3 "rebelliousness" even mean?

I followed your advice and did not click. Thankfully I could view the source.

I agree. I guess in the context of exports a negative value would mean something is imported instead. So for a negative rebelliousness would we assume they are loving ?

Silliness aside, I do wonder why the indicators have negative values.

If you reach zero but you keep clicking answers that make it go lower, what else could it do but go into the negative zone?

We've already talked about this:

I am pretty sure that the displayed percentages are percentages of the absolute value of the previous stat. So -185 "plus" 1.3% would be -182.595. This is to ensure that positive percentages always signify increases and negative percentages always signify decreases, since quite often you'll be more interested in the direction of the change than the exact value.

This is pretty clearly deliberate. Coding the calculation to use absolute values would take more effort than using the "obvious" math, and so is unlikely to have been done by accident.

I'm not sure how the game handles it when a value that was previously exactly zero stops being zero. (Mathematically speaking, that's an increase/decrease of infinity percent.) I think the game describes it as rising/falling by exactly 100%, I recall seeing that once.

Code: Select all

$Rebelliousness = $Rebelliousness - $Reduce_By_This_Much;
IF $Rebelliousness < 0 THEN $Rebelliousness = 0;

We've already talked about this:

ok ok .. sorry!

-3 increased by 100% is - 6

I guess if they didn't remove the sign on the result of the percentage change calculation you'd have stacks of people pointing that out instead.

Sometimes I forget this is a game.

lol. Priceless.

So today I notice this.

Defense Forces
Total War Preparedness Rating -6.32 → -0.00 ⇡100%

-0.00 instead of 0.00

I like it !

-0.00 is generally used, when a negative number is rounded to 0.00 (e.g. -0.0001 rounded to two digits after the decimal point is -0.00). Not only in this game

Quite. If I recall correctly, the Java language specification uses -0.0 to represent float values in exactly such a case.
