C's venerable printf function, which we've been using since day one, prints or writes formatted output to the standard output. As we've seen (by example, if not formally), printf's operation is controlled by its first, ``format'' argument, which is either a simple string to be printed or a string containing percent signs and other characters which cause the formatted values of printf's other arguments to be interspersed with the other text (if any) of the format string.

Suppose we want to print to the screen the approximate value of some variable. For example, maybe we have written a program that calculates mortgage payments based on the amount of the loan, the interest rate, payback period, etc... Since the payment amount is a monetary amount, we don't want to display it to the user with more than two decimal places, but retaining the extra precision in the variable might be useful if it is to be used for some other calculation later -- but how do we do that? How do we print just an approximation of a variable's value (to some number of decimal places)?
