Overview of Display Format Control
Display Format Control:
 Three display formats for X are supported, FIXed SCIentific, and
 ENGineering.  Fixed means fixed number of decimals and settings
 of 0 to 9 are acceptable.

 Scientific format displays X as a 7 digit mantissa and a 2 digit
 exponent.  The 7 digit mantissa always has 1 digit in front of
 the decimal and 0 to 6 digits following the decimal.  While
 scientific formats of 7, 8, and 9 can be specified for internal
 rounding purposes a maximum of 6 decimals will be displayed.
 Clicking the Clear Prefix key (4,2 3,5) will display (for 2
 seconds) all 10 digits of the mantissa as well as clearing any
 pending key clicks.

 Engineering display format is similar to scientific except that
 the exponent will always be a power of 3. In the real HP 11C, the
 value specified for engineering format controls the number of
 additional significant digits displayed after the leading digit.
 In this program the value specified controls the number of
 additional digits displayed after the leading digit.  The
 difference is only noticeable with specific values of X when ENG
 0, 1, or 2 is specified.  Just as with scientific display format,
 values of ENG 0-9 can be specific but a maximum of ENG 6 can be
 displayed.

 To set the display format, click FIX, SCI, or ENG (4,3 1,7 or 4,3
 1,8 or 4,3 1,9) followed by clicking 0-9.
