Question re how PA rounds decimals

[Ginga]

Ok so please try and understand me here;

Advanced Core Extraction by Default takes 24 ticks.

Cathaar get 10% Research Bonus
Engineering 2nd Priority Research gives 10% Bonus

20% of 24 = 4.8 Ticks

Does PA see this as 4 or 5 Ticks?

Advanced Core Extraction should now takes 19 Ticks, yes?

Just working on a plan and need to know this for obvious reasons!

Check the formula in the manual.

total_modifier = engineering_bonus + laboratory_bonus + racial_bonus
 
Final_time = original_time * ((100-total_modifier) /100)

And PA rounds this down. So 10% Cathaar bonus plus 10% engineering bonus means:

24* .8 = 19.2 => 19

PAWiki now has a page about rounding \o/

yes, there's a "Time is rounded down" bit just before the engineering forumlae at the bottom, which got added this beta because it still confused people like me. It also rounds down in the universe screen i think, hence the fact it always adds up to <= 100%

[Ginga]

So it ALWAYS rounds down no matter what the decimal?

[Gerbie]

yes

you would assume that could cause problems?

In what way?

Edit: for example, i am a xan (thus having -1 tick of Production), AND i have Production on 3rd priority (80%). Thus (with 12 ticks being basic production time):

Sov's Production time = (12 - 1)*0.8 = 8.8
This should be rounded down to 8;
"Ordered ships will arrive in 8 ticks." - lo and behold it is.

I added up the percentages of people using the different skins, and it only adds up to 91%. I wonder if this is a rounding error, or if 9% of players are using some other amazing skin, that no-one else knows about.

It's not a rounding error, it's rounding. If 29.2% of people use Skin A, it shows up as 29%, now with the amount of skins there are, that 9% doesn't show up. On the same note, if they rounded up (despite the decimal) all the figures, you'd have over 100%.

I was being sarcastic.

However, it IS a rounding error. I don't mean a mistake, I mean an innaccuracy generated by rounding.
