Accuracy And Capacity Output digits : Up to 10 digits Calculating digits : Up to 24 digits In general, every reasonable calculation is displayed up to 10 digits ± 99 mantissa, or 10-digits mantissa plus 2-digits exponent up to 10 . There is no solution or infinite to the simultaneous equation under VLE mode. There is no real solution to quadratic equation under QE mode. An entry exceeds 84 digits after implied multiplication with auto-correction.

E ­ 10 Mode 0 - MAIN Arithmetic Calculations Arithmetic operations are performed by pressing the keys in the same sequence as in the expression. For negative values, press [ (-) ] before entering the value. See For mixed arithmetic operations, multiplication and division are given priority over addition and subtraction. Results greater than 10 or less than 10 exponential form. See Example 9. 10 -9 are displayed in Display formats Decimal places formats are selected by pressing [ 2nd ] [ TAB ] to display the menu. To set decimal places to n ( F0123456789 ), ] key while the item is enter a n value directly or press [ underlined. (The default setting is floating point notation F and the n value is · ). Even if the number of decimal places is specified, internal calculation for a mantissa is performed up to 24 digits, and the display value is stored in 10 digits. To round off those values to the specified number of decimal places, press [ 2nd ] [ RND ]. Number display formats are selected by pressing [ 2nd ] [ SCI/ENG ] to display the menu. The items on the menu are FLO (for floating point), SCI ( for scientific), and ENG (for engineering). ] or [ ] until the desired formats is underlined, and Press [ ]. then press [ (Note) : The engineering format is similar to the scientific format, except the mantissa can have up to three digits left of the decimal, instead of only one, and the exponent is always a multiple of three. It is useful for engineers to convert units based on multiples of 10 3. You can enter a number in mantissa and exponent form by [ EXP ] key.
