Decimal quantity

[amazlomi]

Dear Alexandre,
First of all, I would like appreciate for your best plugin. Since my store use decmial for products quantity, could you please let me know how can I change it to accept decmial.
I have already installed decimal plugins which let me have decimal quanitities. But when I come to use this plugin, it does not accept even to update decmial quantities under location tab in products. In addition, when we buy a decimal quantity of a product in frontend, it also does not recognize decmials.

looking forward to hearing from you..
my regards,
Ardalan
