Bitwise Shift Left may also be used within expressions for intermediate results; see
Intermediate Assignments, page 253.
Bitwise Shift Right ‘
The Bitwise Shift Right operator shifts the bits of the first operand right by the number of bits
indicated in the second operand. The original LSBs (rightmost bits) drop off and the new
MSBs (leftmost bits) are set to zero. Bitwise Shift Right can be used in both variable and
integer constant expressions, but not in floating-point constant expressions. Example:
X := Y >> 3
If
...the Bitwise Shift Right operator would shift that value right by three bits, setting
Since the nature of binary is base-2, shifting a value right is like performing an integer divide
of that value by powers of two, 2
Bitwise Shift Right has an assignment form,
first operand and the result destination. For example,
X >>= 2 'Short form of X := X >> 2

Bitwise Shift Right may also be used within expressions for intermediate results; see
Intermediate Assignments, page 253.
Bitwise Rotate Left ‘
The Bitwise Rotate Left operator is similar to the Bitwise Shift Left operator, except that the
MSBs (leftmost bits) are rotated back around to the LSBs (rightmost bits). Bitwise Rotate
Left can be used in both variable and integer constant expressions, but not in floating-point
constant expressions. Example:
X := Y <- 4
