Right shift

The shr instructions, short for shift-right, are used for performing a bitwise right-shift, similar to the >>> operator in other languages.

Try it


;; load two numbers onto the stack
i32.const 7   ;; 00000111
i32.const 1   ;; right shift one spot

;; perform a bitwise right-shift

;; the top item on the stack will now be 3 (00000011)
