Manual Calculations
1. Basic Calculations
I Arithmetic Calculations
• Enter arithmetic calculations as they are written, from left to right.
• Use the key to input the minus sign before a negative value.
• 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.
Example Operation
56 Ч (–12) ч (–2.5) = 268.8 56 12 2.5U
(2 + 3) × 10 2 = 500 2

matter how many are required.

Display Range
[SET UP]- [Display] -[Fix] / [Sci] / [Norm]
• Even after you specify the number of decimal places or the number of significant digits,
internal calculations are still performed using a 15-digit mantissa, and displayed values are
stored with a 10-digit mantissa. Use Rnd of the Numeric Calculation Menu (NUM) (page
2-12) to round the displayed value off to the number of decimal place and significant digit
settings.
• Number of decimal place (Fix) and significant digit (Sci) settings normally remain in effect
until you change them or until you change the normal display range (Norm) setting.
