How can I modify the code echo $block->escapeHtml($item->getRowTotal()); to display the value with two digits after the decimal point?

To display the value with two digits after the decimal point, you can modify the code as follows:

echo $block->escapeHtml(number_format($item->getRowTotal(), 2));

The number_format()the function is used to format a number with grouped thousands and a specified number of decimal places. By passing $item->getRowTotal()as the first parameter and 2 as the second parameter, it will format the number with two digits after the decimal point.
