Pdf Invoices Not printing half units

I am needing PDF invoices to print the .5 or 1/2 unit in the invoice thats created. Woocommerce is allowing it and the pricing is right for it but the pdf invoice doesnt show it.

So what i am doing is setting up a order list for a food place that allows half dozen increments. ie 1/2 dz donuts. When the invoice is created for lets say 1.5 dozen it prices it right but prints it as 1. Is there a work around for this?
