Question about rounding up %yeld bonus from location

Postby Hardsun » Fri 01 Mar 2019, 15:22

^ Built my salancedar spot and it got 57 WC (ie 28.5% bonus) - but got only 48% (20 base+28.5 from location) - looks like rounded down.. ?

Image
^ While it was rounded up for our odiemel mine.
Got 39 from location (ie 19.5% bonus) - and ended with 50% in total (30% base +19.5% from location)

How so ? :?

Don't know how to say it in English =/ but in French it's "arrondi au pair le plus proche" :
pair : 2 4 6 8 10 12 .... plus proche = nearest

• 1.5 -> 2
• 1.6 to 1.9 -> 2
• 2.1 to 2.4 -> 2
• 2.5 -> 2
• 2.6 to 2.9 -> 3
• 3.1 to 3.4 -> 3
• 3.5 -> 4
• 3.6 to 3.9 -> 4
• ....

28.5 -> 28
19.5 -> 20

I got that - any X.5 number being rounded to nearest number that can be divided by 2.

But, but ... guys its against math laws :lol:
Always though any x.5+ being rounded up no matter what.

It's just another way to do :D

In English it's also : "round half to even" - RoundingMode.HALF_EVEN always rounds to the next number, like any other rounding-algorithmn - with only one execption: If the number-to-round is exacly between 2 numbers (2.5, 42.5, -4.5), it will not round it up, but instead round it to the neighbour which is even (https://stackoverflow.com/questions/281 ... r#28134961)
Have fun !

:?: Got another question about how exactly rounding works in game.

Lets take grimalrock boulders for example and 66-extraction rails for stone:
Base presence for grock boulders = 1%

1+66/4=1+16.5=17.5 (rounded UP to 18% total presence?)
?? OR is it:
1+66/4=1+16.5(rounded down to 16)=17

Makes a difference since with 17% its 24 cycles to extract each grock boulder and with 18% its 23 cycles.
400/18=22.22 (23 cycles)
400/17=23.53 (24 cycles)

400/18=22.22 (23 cycles)
400/17=23.53 (24 cycles)


I think with a 66 rail, the presence is exactly 17.5 (but rounded up when being displayed, thus showing 18 presence).
We have a quarry for groc boulder with 69 rails. The game shows
18% presence (1+69/4 = 18.25 => round down to 18) but we only need 22 extractions for each boulder.
I think the calculation for number of extractions is
400/(1 + 69/4) = 21.91 (22 cycles).

Another hint is the % the shows after completing each extraction in the log. For groc boulder, here is the % of completion
shown in the game log with 69 rail.
5%, 9%, 14%, 18%, 23%, 27%, 32%, 36%, 41%, 46%, 50%, 55%, 59%, 64%, 68%, 73%, 78%, 82%, 87%, 91%, 96%, 100% (get 1 boulder).
These numbers are rounded for display purpose but they are rounded value of multiples of (18.25 * / 400).


This lead me to think that in the salancedar giantyard (shown in the first post), with a 57 wc mechanism and 20 base, the presence is exactly 48.5% but displayed as 48%.

Im confused :lol: Celine - could you comment this ? ^
Does that mean numbers being rounded for showing purpose and im pretty sure rounded ones used for hero location bonus.
But if Sniq is right - for the purpose of "how many cycles needed" - its used as non-rounded original (hidden) number ?

Its not that critical for my personal salancedar spot, but its more important for guild resources ide say.
And ofc would be nice to know how things actually work - so we can plan properly.

Don't care about energy/time, my Test Character have a speed bonus (x1000).

With rails 66 -> 18% -> 23 cycles.

Remember : this is what I can test on Dev server, I'm not a dev, I haven't access to code, formula etc, I just took some notes when devs and some players (like Gopol, Aknoth,...) gave some intersting "maths" information.

I never test on dev'server for myself, I'm so late in game that I ask question to "big guild" members :p
"what do I need for a "small" or "big" quarry for giant grim ?"...."Do I need a super sleeping place, or is a normal one enoug ?"
(thank you Fiergrue server ^^)

Thanks again - both Celine and Sniq.
But at least you can do such testing while its being too expensive to do similar things for me.

... and "With rails 69 -> 18% -> 22 cycles." proves what Sniq posted before... so its indeed

400/(1 + 69/4) =400/18.25=21.92 (22 cycles)
and NOT
400/ROUNDED_(1+69/4)=400/18=22.22 (23 cycles)

Arghh - i was calculating it wrong for almost 2 years. Better late then never :lol:

Based on the above (which was extremely interesting). There is a possibility that the real chance in the example above of the salanсedr spot is 48.5 and only displayed as 48, on the principle "Banker's rounding". I mean mathematical calculations can differ from rounding off. So using the best engineer items can still make sense

N'oubliez pas que Silverlight sous Mac ne calcule pas toujours exactement de la même façon.
