As test.png, when I tried computeInterestIncrement(1000 : 100 : 12 : i), 
but it still raise an error again like split test2

And when I entered computeInterestIncrement(1000 : 100 : 12 : -i), it 
would be fine like split test1.

However, as test2.png if I filled the form, and didn't key enter to 
finish, I just directly clicked the bottom right button, it would be fine.

But when I want to edit it, it raised an error again.
