The constant function works with
whole numbers, decimals, and

the total appears on the second
line at the right of the display. The
counter shows how many times the
constant has been repeated. If the
number at the right exceeds 6
digits, the counter will not be
shown. The counter returns to 0
after it reaches 99.

constant function, subsequent
calculations are performed with
the quotient portion of the result.
The remainder is dropped.
