Sale currency

Please tell me why I can not supply a ratio of 0.7 or 0.3 or 0.1 for the sale of currency? I use the tab for currency. But for sale for some reason only coefficients 0.5 or 1 and above are used.

If you use a decimal it gets rounded to prevent people from slightly underpricing in order to appear first on the listings (which used to be a big problem with everyone listing things for X.99, then X.98, etc, etc). To list bulk items you need to use fractions. e.g. ~b/o 3/7 chaos means you want to sell 7 whatevers for 3 chaos.
