Question

For the first problem set, I would like to round the remaining balances to the nearest penny. The function
round(balance, 2)
doesn't seem to do anything....what's the right way to do this?

Answer 1

to be clearer, if for example the result is $16.00 dollars, for example, I will get the output $16.0 dollars

Answer 2

That's a print formatting issue. In C style syntax the format string would be "$%4.2f"
For a 4 digit, 2 to the right of the decimal float number.
