variables printing incorrect in defined function

Question

Currently I'm trying to build a program that counts cash and change. When I am adding certain change though, it immediately calculates wrong and it is visible. It takes a few attempts to get it to occur but following these steps will cause the occurence.

1: Start the program by using python3 countcash.py

2: Press 1 to set 1 dollar bills to any # Enter number of ones: 15

3: Than begin adding random amounts of different change (pennies etc.)

Overtime it will begin to show the total as something like this Total = 15.99999999907

Now get ready... Here is all the code so far, all you have to do is possibly install a few of the imported libraries, than save with the .py extension and this is compatible with debian and windows systems!
