When you turn on the HP-lOB for the first time, numbers
are displayed with two decimal places and a period as the
decimal point. The display format controls how many digits
appear in the display.
If the result of a calculation is a number containing more
significant digits than can be displayed in the current display format, the
number is rounded to fit the current display setting.
Regardless of the current display format, each number is stored internally
as a signed, 12-digit number with a signed, three-digit exponent.
