Decimal Point Selector
Fixed decimal point mode; these settings specify the number of digits
to the right of the decimal point that are shown in the result.
Floating decimal point mode; this setting specifies that all digits of the
result be shown up to a maximum of 12 digits. If the result exceeds
these capacities, excess digits to the right of the decimal point are
dropped. No rounding takes place.
Rounding Selector
Absolute round up.
This setting causes automatic round off. If the last digit of the result
that will be printed or printed/displayed upon rounding is followed by a
value of 0 to 4, the digit is unchanged. If the last digit of the result that
will be printed or printed/displayed upon rounding is followed by a
value of 5 to 9, the digit is rounded up.
Absolute round down (truncation).

position.
