• 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 dis-
played 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 deci-
mal place and number of significant digit settings.
• Number of decimal place and number of significant digit settings remain in effect
until you change them or until you change the exponential display range (Norm)
setting.
• To change the exponential display range (Norm) setting, press 3 (Norm) while
the display format (Display) menu is on the screen. Each time you perform this
operation, the range toggles between the following two settings.
Norm 1 ............ exponential display for values outside the range of 10 –2 to 10 10
Norm 2 ............ exponential display for values outside the range of 10 –9 to 10 10
