Bitwise Rotate Right '->', '->='

The Bitwise Rotate Right operator is similar to the Bitwise Shift Right operator, except that the LSBs (rightmost bits) are rotated back around to the MSBs (leftmost bits). Bitwise Rotate Right can be used in both variable and integer constant expressions, but not in floating-point constant expressions.

Example:

X := Y -> 5 

If Y started out as:

%10000000 01110000 11111111 00110101

...the Bitwise Rotate Right operator would rotate that value right by five bits, moving the original five LSBs to the five new MSBs, and setting X to:

%10101100 00000011 10000111 11111001

Bitwise Rotate Right has an assignment form, ->=, that uses the variable to its left as both the first operand and the result destination. For example,

X ->= 3'Short form of X := X -> 3 

Here, the value of X is rotated right three bits and is stored back in X. The assignment form of Bitwise Rotate Right may also be used within expressions for intermediate results; see Intermediate Assignments.
