Basic Calculations (COMP)
This section explains how to perform arithmetic,
fraction, percent, and sexagesimal calculations.
All calculations in this section are performed in the
COMP Mode ( (MODB[1]) .
* For more information, see "Specifying the
Number of Display Digits".
Omitting a Final Closed Parenthesis
You can omit any closed parenthesis ()) immediately
preceding operation of the E) key at the end of a
calculation.
This is true only in the case of Linear format.
E Arithmetic Calculations
Use the [+], [=], CJ and (=) keys to perform arithmetic
calculations.

Number of Decimal Places and Number of
Significant Digits
You can specify a fixed number of decimal places
and significant digits for the calculation result.

displayed as improper fractions.
* Mixed fraction input is possible only when "ab/c"

* If the total number of digits used for a mixed
fraction (including integer, numerator,
denominator, and ceparcier symbols ) is greater
than 10, the value is automatically displayed in
decimal format.
* The result of a calculation that involves both fraction
and decimal values is displayed in decimal format.
