As discussed on Abiility to have decimal quantities this module alters the necessary forms to order certain product types with a decimal quantity. An example of this would be to purchase 4.3 metres of fabric.
Currently it is only set up to handle one unit of conversion, being metres, however it can be improved to handle any other unit of measurement. All it does is multiply out the decimals to store in the database and then divide back in to decimals for display to the user.
I would really appreciate any feedback and would like to know if anyone experiences any issues with it.
