Arithmetic calculation

• Arithmetic operations are performed by pressing the keys in the same
sequence as in the expression. See Example 6.
• For negative values, press [ (–) ] before entering the value. See Example
7.
• For mixed arithmetic operations, multiplication and division are given
priority over addition and subtraction. See Example 8.
• Results greater than 10
form. See Example 9.

Display formats

• Decimal 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 [ ENTER ] key while the item is underlined. (The default
setting is floating point notation F and the n value is • ). See Example 10.
• Even if the number of decimal places is specified, internal calculation for
a mantissa is performed in 14 digits for SRP-285 and 24 digits for SRP-
280, 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.
