Amount and price format

Hello! Questions about documents: 1. In the invoice and in the act, in the columns "Price" ({row: product_productprice}) and "Amount" ({row: product_sumoriginal}), sums without kopecks are printed, if the number of kopecks is 0. How to print amounts with two decimal places anyway? In the cell "Total" ({ordersum}), the sum is displayed with two decimal places in any case. 2. Is it possible to set up so that the number of the act, the invoice corresponds to the number of the account, according to which the act/expenditure is issued? 3. How to insert a header and footer with the page number and (on the screen) into the document? Thanks in advance for your help! [file]2613[/file]
