If a mixed number or a whole number is input, it will first be converted to an
improper fraction before being converted to a decimal. This will require a press of
the
key after inputting the problem.
The calculator does not round answers. When an answer contains more decimal
places than will fit on that line of the screen, any additional places will be left off
(truncated).
Once the
key is pressed, all other calculator keys are disabled except the
key,
key, and
key. To reactivate these keys, start over with a
new calculation.
