<< bitwise left shift operator
expression1 << expression2
Converts expression1 and expression2 to 32-bit integers, and shifts all the bits in
expression1 to the left by the number of places specified by the integer resulting from the
conversion of
expression2. The bit positions that are emptied as a result of this operation are
filled in with 0 and bits shifted off the left end are discarded. Shifting a value left by one
position is the equivalent of multiplying it by 2.
