* All amounts calculated when f! is pressed are automatically rounded to the number of
decimal places specified by the display format. (The display format is described in Section 5.)
This rounding affects the number inside the calculator as well as how the number appears in
the display. The amounts calculated on your hp 12c may differ from those on the statements
of lending institutions by a few cents, since different rounding techniques are sometimes used.
To calculate answers rounded to a different number of decimal places, press f followed by
the number of decimal places desired before you press f!.
