Notes
The examples on the transparency
masters assume all default
settings.
The result of Integer Divide £
always appears as quotient and
remainder (__ r __).
The maximum number of digits for
quotient or remainder (r) is 5.
Quotient, remainder, and the r
character cannot total more than
10 characters.
If you use the result of integer
division in another calculation, only
the quotient is used. The remainder
is dropped.
All numbers used with £ must
be positive whole numbers.
If you attempt to divide by 0, an
error message is displayed.
T, U, V, W, ®, and £ work
with the built-in constants.
