push_rotate

Declaration: void push_rotate (EStackIndex i , EStackIndex j )
Category(ies): Math
Description: Rotates the elements of an integer, a list, or a string to the left or right.
Inputs: i
j
Outputs: Pushes a rotated copy of i onto the estack.
If i is an integer, then the bits are rotated.
If i is a list, the elements of the list are rotated.
If i is a string, the characters of the string are rotated.
If j is positive, the rotation is that number of places to the left.
If j is negative, the rotation is that number of places to the right.
Each time the input is rotated left, the leftmost element (integer bit, list
element, string character) that is pushed out is moved to the rightmost
position.
Each time the input is rotated right, the rightmost element that is pushed
out is moved to the leftmost position.
Assumptions: None
Side Effects: May expand the estack, cause heap compression, or throw errors if
arguments are invalid
Availability: On AMS 2.00 and higher.
