Display Control
When you turn on your HP-11C, because of Continuous Memory,
the display setting will be the same as it was before you last turned
off the calculator. But regardless of the display options in effect,
the HP-11C always internally represents each number as a 10-digit
mantissa and a two-digit exponent of 10. Thus, when the calculator
is set to display only four digits past the decimal point, the fixed
constant pi, for example, appears in the display as 3.1416.
However, pi is always represented internally as 3.141592654 X 10%.
3.141592654 X 10°°

following illustration shows how the number 123,456 would be
displayed by a 4-digit setting in each of the three modes.
