• 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 2-4-1) to round the displayed value off to the number of decimal place and number
of significant digit settings.
• Number of decimal place (Fix) and number of significant digit (Sci) settings normally
remain in effect until you change them or until you change the normal display range
(Norm) setting.
