Calculate exact change needed using US currency worth less than a dollar

Change Calculator

Calculates exact change needed using US currency worth less than a dollar. Underlying algorithm is recursive in nature and is powered by decimal.Decimal

About

I was shown this algorithm in a comp. scie class a few years back and wanted to try implementing it on my own.

Example

change_calculator = ChangeCalculator()
change = self.change_calculator.calculate(.99)
self.assertEqual(change.pennies, 4)
self.assertEqual(change.nickels, 0)
self.assertEqual(change.dimes, 2)
self.assertEqual(change.quarters, 3)
