●
or (Shift): these keys shift the bits one space to the left (or right). With each press, the
new integer represented appears in the Out eld (and in the hex and decimal elds below it).
●
or (Bits): these keys increase (or decrease) the wordsize. The new wordsize is
appended to the value shown in the
Out eld.
●
(Neg): returns the two’s complement (that is, each bit in the specied wordsize is inverted
and one is added. The new integer represented appears in the Out eld (and in the hex and decimal
elds below it).
●
or (Cycle base): displays the integer in the Out eld in another base.
Menu buttons provide some additional options:
: returns all changes to their original state
: cycles through the bases; same as pressing +
: toggles the wordsize between signed and unsigned
: returns the one’s complement (that is, each bit in the specied wordsize is inverted: a 0 is
replaced by 1 and a 1 by 0. The new integer represented appears in the Out eld (and in the hex and
decimal elds below it).
: activates edit mode. A cursor appears and you can move about the dialog using the cursor
keys. The hex and decimal elds can be modied, as can the bit representation. A change in one such
eld automatically modies the other elds.
: closes the dialog and saves your changes. If you don’t want to save your changes, press
instead.
3. Make whatever changes you want.
4.
To save your changes, tap ; otherwise press .
NOTE: If you save changes, the next time you select that same result in Home view and open the Edit
Integer dialog, the value shown in the Was eld will be the value you saved, not the value of the result.
