„Arithmetic Calculations

zArithmetic operations are performed by pressing the keys in the same sequence as in the expression. See Example 6.

zFor negative values, press [ (−) ] before entering the value. See Example 7.

zFor mixed arithmetic operations, multiplication and division are given priority over addition and subtraction. See Example 8.

zResults greater than 10 10 or less than 10 -9are displayed in exponential form. See Example 9.

„Display formats

zDecimal places formats are selected by pressing [ 2nd ] [ TAB ] to display the menu. To set decimal places to n ( F0123456789 ),

enter a n value directly or press [ ] key while the item is underlined. (The default setting is floating point notation F and the n value is • ). See Example 10.

zEven 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 ]. See Example 11~12.

z 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).

Press [

] or [

]

until the desired formats is underlined, and

then press [

].

See Example 13.

(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.

zYou can enter a number in mantissa and exponent form by [ EXP ] key. See Example 14.

„Parentheses Calculation

zOperations inside parentheses are always executed first. The calculator can use up to 13 levels of consecutive parentheses in a single calculation. See Example 15.

zClosed parentheses occurring immediately before operation of the

[ ] key may be omitted, no matter how many are required. See Example 16.
