The /e modifier on your substitution says that the substitute string is to be evaluated as a perl expression. The '<<' operator is 'shift left', corresponding to multiplication by a power of two. The '|' operator is 'bitwise or', not alternation. See perlop for details.

Update: The & operator is 'bitwise and'.
