Square for WooCommerce

I sell some items by unit prices and others by weight. I’ve added some basic functionality myself to handle this on the WooCommerce end, but syncing the inventory with Square does not work–the inventory changes in the WooCommmerce Square plugin are all set as integers in every function (even though Square itself does allow selling products by weight or other non-integer units), so the inventory changes are always getting rounded up or down when comparing with or adjusting the Square inventory numbers.
