Divisor shows you how much each item in a stack costs at the auction house. For example, if there were 5 motes of fire available for a 12g 50s buyout, Divisor would inform you that each mote of fire would cost you 2g 50s, and that 10 of them would cost you 25g.
Divisor is installed like pretty much every other World of Warcraft mod on the planet. Extract the contents of the zip file to your Add-ons folder, generally located here:
C:\Program Files\World of Warcraft\Interface\Addons
To try out Divisor, visit an auction house, and search for something that's typically sold in stacks. For example, try searching for "healing potion". Then, hover over the price of any stack of healing potions (more than one). Divisor will tell you the per-unit cost in a tooltip on the right. There's nothing you need to do to turn on Divisor or configure it; when it's installed, it's working.
The numbers you see may occasionally be a little different from what you're expecting. The most likely cause for this is that Divisor automatically factors the minimum bid increment into the calculations. Take this example: Let's say there are 2 Arcane Tomes for sale, at a price of 28g 1s, or 29g buyout. You may initially expect Divisor to tell you that the bid for 1 would be 14g 50c, since that's half of 28g 1s. However, someone has already bid the minimum on these, so you'd have to increase the bid to at least 29g 41s, 5% more than the current price. That's more than the buyout. So, Divisor doesn't even display a minimum bid amount, and just displays "Buyout 15g 50s". Since you probably installed Divisor to help you get better deals on odd-sized stacks of items, it's showing you the exact per-unit amount it would cost you to either bid the least amount possible, or buy the item outright.
Certain items are mostly useful in stacks. This includes the various primal motes (Mote of Fire), enchanting lesser essences (Lesser Astral Essence), and rep items (Sanguine Hibiscus). For some of these items, in addition to the single item price, Divisor will tell you the cost to buy a stack of them. The stack size depends on the item—enchanting essences "stack" to 3 (even though a stack technically holds more than 3), motes "stack" to 10, since that's how many it takes to make a primal, and so forth.
Divisor supports a few slash commands that you can type into chat to customize Divisor.
Divisor automatically gives you individual prices for all items in the auction house, and stacked prices for certain items. For example, if someone were selling 3 Mote of Fire, Divisor would show you the price for 1 Mote of Fire, as well as 10 Mote of Fire. If you want to add your own items for Divisor to show stack prices, you can use the /divisor stack command.
/divisor stack number [item]
/divisor stack 20 [Netherweave Cloth]
/divisor stack 20 Silk Cloth
You can undo the effects of the /divisor stack command by using the /divisor unstack command.
/divisor unstack [item]
/divisor unstack [Netherweave Cloth]
/divisor unstack Silk Cloth
If you've really screwed up and want to go back to the default Divisor options, you can use /divisor reset.
/divisor reset
You can see all of the stack sizes you have set (as well as all of the ones that came with Divisor) using the /divisor list stacks command.
/divisor list stacks
I welcome your feedback. The best way to contact me is through the Divisor page on IncGamers. You can also contact me through in-game mail: Vger on Azjol-Nerub (US), Horde. (Just make sure that, if you want a reply to an in-game mail, you keep an alt on my server and check mail from time to time. I won't have a character already on your server, and I don't want to have to create an alt and run to a mailbox just to write back.) Also, check out my official site, with links to my other mods.
When reporting bugs, it's helpful to be as specific as possible. As of the WoW 2.1 patch, WoW hides mod error information from you. Reenabling it in Interface Options would be helpful; the error text includes useful information about where the error occurred. Installing a mod like Swatter can provide even more useful error information that can help Vger track down the bug.
There are no known bugs right now. See the "future versions" section for things that aren't necessarily bugs but I might improve someday.
