Word Size and Window Display
The HP-16C will work with words (data units) up to 64 bits long.
The default word size when you first turn on the calculator or reset
Continuous Memory is 16 bits. The display window shows eight
digits at a time; leading zeros are not displayed.* A period is placed
on the left and/or right side of the h, d, o, or b to indicate the
presence of more, undisplayed digits to the left or right of the
currently displayed portion of a number.
*Setting flag 3, as explained later in this section (page 36), will cause all leading zeros to
be included in the display.
