In eCart there is a function that is used to display the currency values, it is:
WA_eCart_DisplayMoney()
It will format a value to display as money including the currency symbol and decimal places. How the currency is formatted with the function will depend on how you have these values setup in your cart object. Here is an example of what the price might look like on a page with this function:
<?php echo WA_eCart_DisplayMoney($eCart1, "25.89"); ?>
This will include the currency character and other formatting that is setup in the cart object.
