Do beware the inherent imprecision of floating-point values. Note that a bite of this size would whittle what was a 41¢ problem down to a 16¢ problem, since 41 - 25 = 16. I'm taking CS50, an Introduction to CS, and we're asked to do the following task: Suppose that a cashier owes a customer some change and in that cashier’s drawer are quarters (25¢), dimes (10¢), nickels (5¢), and pennies (1¢).
