None of my code will help you. These are examples, you need to change your code to match the same methods with preference on using locale aware functions such as money_format. Find where you need to change the monetary displays and use money_format, and where you need to find integer values rounded up use the ceil() function. You can change the variables themselves, but I would suggest you either make a new variable with the output formats changed or you do it directly within the output. This lets you make further use of the variables if you need to do more calculations later with them. Sometimes rounded does make sense; the number of days variables can be rounded to an even integer number when calculated since it's highly improbable that there are any fractional days provided. These are all based on whatever the business rules are for the application.
