           <p>The abstract operation NumberBitwiseOp takes arguments _op_, _x_, and _y_. It performs the following steps when called:</p>
           <emu-alg>
             1. Let _lnum_ be ! ToInt32(_x_).
-            1. Let _rnum_ be ! ToUint32(_y_).
+            1. Let _rnum_ be ! ToInt32(_y_).
             1. Return the result of applying the bitwise operator _op_ to _lnum_ and _rnum_. The result is a signed 32-bit integer.
