TypeError: float() argument must be a string or a number

My shop does not have a tax for shipping prices.
After edit of sale.py commenting this:
ship_tax_vat = float(data_record['shipping_tax_amount'])/float(data_record['shipping_amount'])
and assign a value of 0 to ship_tax_vat by:
ship_tax_vat=0
error is then bypassed
