  • nExpression1
    Specifies the numeric value whose bits are shifted to the left. If nExpression1 is not an integer, it is converted to an integer before its bits are shifted.
  • nExpression2
    Specifies the number of bit positions to shift. If nExpression2 is not an integer, it is converted to an integer.
