With approx, calculation results are displayed using exponential notation. As with
the RUN Mode, the mantissa can have up to 10 digits and the exponent up to two
digits. The number of digits that can be input for approx depends on the setting of
the set up screen's Display item.
Example 6(g g g g g )6(g g g g g )1(appr)jMcaw (Display: Norm1)
