Question

I'm a bit picky about my answers vs the problem set answers, so I was hoping someone could help me out with some seemingly rounding issues.

My answers on PS1, problem 1 is
Total: 1131.11
Remaining: 4611.48

Test Case 1 Answers
Total: 1311.12
Remaining: 4611.46

I started off fine and then noticed down in months 6 and greater I was occasionally losing or gaining a penny. I rounded everything at the print level. Should I be rounding it before that?

Answer 1

In finance, they typically want whole pennies. This makes it so you need to clean up every calculation and in real things they may even deal with everything as integers so there is no error.
