You need to format the number using number format PHP function. Consider

$price = 125;
$quantity = 1;   
echo number_format($quantity*$price,2);

You can also have extra comma separated values that set the decimal separator, i.e. "." and the thousands separator also i.e. ",". See http://php.net/manual/en/function.number-format.php
