Extending integers to 2 decimal places (displaying total price)

[WebDeveloperMike]

Hi everybody,

 

I would like to show a total dollar amount to customers with 2 decimal places, my php code is rendering things like this: $19.4 when I want it to show something like this: $19.40 - so basically just need to know how to extend it to 2 decimal places. Its probably pretty simple but i have been unsuccessful in my findings! Thanks!
