About Calculation Capacity

The following will cause "E" to appear on the display to indicate that the
capacity of the calculator is exceeded.

*   When ever the integer part of a result (whether intermediate or final)
    is longer than 8 digits.  In this case, the display shows the most
    significant digits of the result.  The true decimal point of the
    result is 8 places to the right of the decimal position shown on the
    display.

Calculation Examples

Example                            Operation                       Display

                                          AC                            0.

53 + 123 - 63 =             53 + 125 (Error)        +                 125.

                                       C 123        +                 123.

                                      - 63 =                          113.

963 x (23 - 56)=             23 - 56 x 963 =                      - 31779.

(56 x 3-89)/5.2 + 63 =     56 x 3 - 89 / 5.2

                                      + 63 =                     78.192307

123456 x 741852 =          123456 x 741852 =        E            915.86080

                                           C                     915.86080

                                          AC                            0.
