I have items that I'd rather not sell for a full RP, so I set the item to sell for 0.02.

When I sell 100, it says I got 1 RP.

Additionally, the message that comes up says it was sold for 0 RP.

I see decimals in the sales data file so I assume it's supported.

Thanks.

I tested this another way.

If I mark an item as being worth 3.5 RP, selling it when I have 0 RP shows 3 RP. Selling it again shows 6 RP. 

It appears despite the configuration showing numbers in decimals, it doesn't actual work with fractions of a whole.
