Arithmetic Calculations
• Enter arithmetic calculations as they are written, from left to right.
• Use the - key to input a negative value.
• Use the - key for subtraction
• Calculations are performed internally with a 15-digit mantissa. The result is
rounded to a 10-digit mantissa before it is displayed.
• For mixed arithmetic calculations, multiplication and division are given priority
over addition and subtraction.

“(2+3)E2” does not produce the correct result. Be sure to enter this calculation as
shown.
*
2
Final closed parentheses (immediately before operation of the w key) may be omitted, no
matter how many are required.
*
3
A multiplication sign immediately before an open parenthesis may be omitted.

4
This is identical to 6 / 4 / 5 w.

Number of Decimal Places, Number of Significant Digits,
Exponential Notation Range
• These settings can be made while setting up the display format (Display) with
the set up screen.
• Even after you specify the number of decimal places or the number of signifi-
cant digits, internal calculations are still performed using a 15-digit mantissa,
and displayed values are stored with a 10-digit mantissa. Use Rnd (4) of the
Numeric Calculation Menu (NUM) to round the displayed value off to the
number of decimal place and significant digit settings.
