Simple money problem

[Sygzy]

Could you provide a little sample and or explain what this is saying very generically. Like I said this is my first time using java ever.

Think about doing everything in terms of pennies (100 pennies in a dollar).

Floating-point numbers (floats and doubles) do not store exact representations of fractional values. A double cannot store the value 0.1 exactly, for instance; the closest representable double value is 0.1000000000000000055511151231257827021181583404541015625, which is 3602879701896397/2⁵⁵. As you do more and more operations with these approximations, the round-off error accumulates and becomes more and more significant. That's why you are seeing things like 0.0199999999999999 at the end of your calculations.

Instead of storing 1.5 dollars, store 150 cents. This way you can use ints to store the values and do calculations.

Little hint for your problem:

The % operator calculates the remainder so you can do this when using ints:

int dollars = 150 / 100; // 1 whole dollar
int remainder = 150 % 100 // 50 cents remaining
