|0001447||Dwarf Fortress||Dwarf Mode -- Trade||public||2010-04-22 23:06||2010-07-20 08:40|
|Assigned To||Toady One|
|Priority||low||Severity||minor||Reproducibility||have not tried|
|Target Version||Fixed in Version|
|Summary||0001447: Gold nuggets weigh 901352|
|Description||In the trade display gold the weight format is not wide enough and the weight value (1352) runs into the sale value (90) and overwrites the dwarf-bucks symbol.|
Anyway 1352 is unreasonably large given that anvils weigh only 78 and the entire caravan's weight capacity was 3100. So instead of fixing the format you could just set a max weight of 999 for any one item.
|Steps To Reproduce||strike the earth, find gold, trade nugget.|
|Tags||item, trading, user interface, weight|
|Does this reproduce? That value seems awfully high.|
|I can vouch for that, I get the same thing.|

Btw examining a gold nugget shows its weight is 1352. Anyone with gold can repro this easily. So it's simply a display format error that the value (90) runs into the weight (1352). But I think 1352 is too high anyway.
24kt gold is 1204 lb/ft3 and cast lead is 708 lb/ft3, the ratio is 1.7:1.
In game a bar of lead (weight 22) and a bar of gold (weight 38) closely match this ratio, implying that a bar of lead in game is the same size as a bar of gold. Since you get one bar of lead from a galena boulder, which weighs 525, there's a smelting reduction factor of 23.86. And since you get one gold bar weighing 38 from smelting a gold nugget weighing 1352, the gold smelting reduction factor is much higher, 35.58, implying that a gold nugget is much less pure gold than a galena boulder is pure lead.
That doesn't match my intuition about gold nuggets, which is of course based on movies and not science.
Just using the lead smelting reduction factor for gold would mean gold nuggets should weigh 907 (38*23.86). Or 525*1.7 is 983, so I think gold nuggets should weigh no more than 907.
|There is some general funniness with the way weight is calculated currently. See 0001386 and 0000297.|
|This seems unrelated to 0001386 and 0000297, which are internal calculation errors. This actually follows directly from the raws; gold nuggets *are* pure gold, and have a solid_density of 19320. Galena has a solid_density of 7500. But all boulders are created the same, so the 'gold nuggets' weigh significantly more than the galena boulder.|
nice report. Allowing for some variance in purity from one material to the next the weight for gold could be working as intended. raw ore is awful darned heavy, and isn't necessarily all on the same ratio before smelting.
In either event, this does still leave a misleading display error.
Reminder sent to: Toady One
Hey Toady -- another weight bug that was possibly fixed already.

|That one is kind of in a weird space. The boulders are human-sized, so a gold boulder ("nuggets") is quite heavy -- 1300kg seems reasonable. The reason they are human-sized is because you can make giant statues from them (as well as like three goblets). Shrinking/growing is inevitable until more reactions respect sizes etc., and I'm not even sure how good of an idea that'll end up being, though it's more important to do for adv mode.|
