shift()
Catalog >
If #ofShifts is positive, the shift is to the
left. If #ofShifts is negative, the shift is to
the right. The default is −1 (shift right one
bit).
In a right shift, the rightmost bit is dropped
and 0 or 1 is inserted to match the leftmost
bit. In a left shift, the leftmost bit is
dropped and 0 is inserted as the rightmost
bit.
For example, in a right shift:
Each bit shifts right.
0b0000000000000111101011000011010
Inserts 0 if leftmost bit is 0,
or 1 if leftmost bit is 1.
produces:
0b00000000000000111101011000011010
The result is displayed according to the
Base mode. Leading zeros are not shown.
Important: To enter a binary or
hexadecimalnumber, always use the 0b or
0hprefix (zero, not the letter O).
