Example: A Savings Account. You deposit $2,000 into a savings
account that pays 7.2% annual interest, compounded annually. If you

account to grow to $3,000? Since this account has no regular payments
(PMT=0), the payment mode (End or Begin) is irrelevant.

amount: the rounded number $894.33, an exact dollars-and-cents amount.
