shift()
CATALOG
integer1
shift(
Shifts the bits in a binary integer. You can enter
integer1
automatically to a signed, 32-bit binary form. If
the magnitude of
form, a symmetric modulo operation brings it
within the range.
If
#ofShifts
#ofShifts
default is ë 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:
0b00000000000001111010110000110101
Inserts 0 if leftmost bit is 0,
or 1 if leftmost bit is 1.
produces:
0b00000000000000111101011000011010
The result is displayed according to the
mode. Leading zeros are not shown.
