rotate()
MATH/Base menu
integer1
rotate(
Rotates 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.

the right. The default is ë 1 (rotate right one bit).
For example, in a right rotation:
Each bit rotates right.
0b00000000000001111010110000110101
produces:
0b10000000000000111101011000011010
The result is displayed according to the
