Return amount refunded as a float 

An amount refunded should be numeric, I was receiving pHP notices that a non numeric value was encountered. Seems this is something potentially new as of PHP 7.1? Is there any reason we should **not** return a float here? Any null or empty response from the SQL query would be 0, which would still be accurate for the total that was refunded for that order.
