I'm using Magento 1.8 and I am amazed that I cannot get the system to allow orders of 0.1 quantity. I'm building this stor to sell fabrics, per 10cm's. So that would be 0.1meters and I do not want the quantity to represent centimeters.
I've tried the qty_increment field in the Admin > System > Configuration > Inventory but it only accepts full integers. :-(
Anybody know how to solve this or is Magento simply not meant for this ?
