Use below code to round off the total amount

#set($round = $ticket.roundDouble($ticket.getTotal(),0) - $ticket.getTotal())
<line>
  <text align="left" bold="true" length="12">Round Off</text>
  <text align ="right" length="36" bold="true">$ticket.formatCurrency($round)</text>
</line>
<line size="1">
  <text align="left" bold="true" length="12">Total.</text>
  <text align ="right" length="36" bold="true">$ticket.formatCurrency($ticket.roundDouble($ticket.getTotal(),0))</text>
</line>

Amount can be rounded in many ways.
To round the amount to nearest 0.25, use the below code

#set($round = $ticket.getTotal() / 0.25 )
#set($round = $ticket.roundDouble($round, 0) * 0.25)
#set($roundoff = $round - $ticket.getTotal())
<line>
  <text align="left" bold="true" length="16">Round Off</text>
  <text align ="right" length="26" bold="true">$ticket.formatCurrency($roundoff)</text>
</line>
<line size="1">
  <text align="left" bold="true" length="16">Total.</text>
  <text align ="right" length="26" bold="true">$ticket.formatCurrency($round)</text>
</line>

To round the amount to nearest 5, use the below code

#set($round = $ticket.getTotal() / 5 )
#set($round = $ticket.roundDouble($round, 0) * 5)
#set($roundoff = $round - $ticket.getTotal())
<line>
  <text align="left" bold="true" length="16">Round Off</text>
  <text align ="right" length="26" bold="true">$ticket.formatCurrency($roundoff)</text>
</line>
<line size="1">
  <text align="left" bold="true" length="16">Total.</text>
  <text align ="right" length="26" bold="true">$ticket.formatCurrency($round)</text>
</line>

The above scripts need to paste below the scripts for Total after the <!– TAXES END–> (It should be pasted exactly between the lines </line> and <line></line>

After pasting the script it should look like the one in the picture below:

Use below code in event.total to add round off as an item to the bill.
First create a product with barcode “roundoff”.

//ROUND OFF
double step = 0.005;
int decimals = 3;
int numlines = ticket.getLinesCount();
for (int i=0;i<numlines;i++)
{
    if(ticket.getLine(i).printCode()!=null && ticket.getLine(i).printCode().equals("roundoff"))
    {
        ticket.removeLine(i);
    }
}
double total = ticket.getTotal();
double round = total % step;
if(round > 0 && ticket.roundDouble(round, decimals) < step)
{
    //ALWAYS STEP DOWN
    sales.addItemByPrice("roundoff", round * -1);
}

Save & restart
