• 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 of the Numeric Calculation Menu (NUM)
(page 2-4-1) to round the displayed value off to the number of decimal place and
signifi cant digit settings.
• Number of decimal place (Fix) and signifi cant digit (Sci) settings normally remain in effect
until you change them or until you change the normal display range (Norm) setting.
Example 100 ÷ 6 = 16.66666666...
