Notice that rounding can occur to the left of the decimal point, as in
the case of ENG 0 specified above.


When engineering notation has been selected, the decimal point shifts to
maintain the exponent of 10 as multiple of three. For example, multiplying
the number now in the calculator by 10 twice causes the decimal point to shift
to the right twice without altering the exponent of 10.




However, multiplying again by 10 causes the exponent to shift to another
multiple of three. Since you specified ENG 2
earlier, the calculator maintains two significant digits after the first
one when you multiply by 10 again.




Automatic Display Switching and Scrolling


The HP41C automatically switches the display from fixed point notation
to scientific notation whenever the number is too large or too small to be
seen with a fixed decimal point. This keeps you from missing unexpectedly
large or small answers.
