1. 2 cents worth of Rounding calculations

Irv has added a really neat print.pdf routine to his EUGTK amortization program: http://sites.google.com/view/euphotos/home Hey, Irv, how about adding the snippet programing samples to your examples or utilities folder - maximize exposure.

```Examples below using Irv Mullins EuGtk version of amort.ex
Same results using my console based amort.ex
```

```                   -- Without rounding
monthly_payment=balance_remaining*(monthly_interest/(1.0-power(1.0+monthly_interest,-n_payments)))
payment_allocated_to_interest=balance_remaining*monthly_interest
```

``` Principal = \$10,000  Interest=18   # of payments = 12                                                                          -------------------------------------10,000.00
