Greetings all,

I'm a greenhorn, and I need a little help. I had a little free time at work today and was trying to come up with some example script ideas for practice, and after hearing my wife complain about the credit card bills lastnight, I came up with the one below. Everything in the example works like I wanted/expected, except for the formatting of the double currentTotal. I'm not exactly sure yet how to format the output to where it only displays 2 places after the decimal: $219.79 vs. $219.79255898393723. I've included my sample code and output below (please forgive me...output is long). Any suggestions? Thanks in advance! -Brock

/**********************************************************

* This example should take the total of the credit card,

* add the monthly interest rate to the total and display

* how much you owe at the time of making a payment.

* Then it should subtract the payment and show how much

* you owe after the payment. It should repeat itself until

* you no longer owe anything. It will also show how many

* total months it takes to pay the darn thing off. That is

* provided you don't put anything else on the card like

* dinner at Chili's or Applebee's. =)
