* For displayed values, the calculator selects the ENG sym-
bol that makes the numeric part of the value fall within
the range of 1 to 1000.
* ENG symbols cannot be used when inputting fractions.
* The ENG mode cannot be used in combination with the
CMPLX, or BASE-N modes.
• Performing any of the key operations in the above table
while you are not in the ENG mode inputs the exponen-
tial value in the “Unit” column (without inputting the ENG
symbol).
