Additionally for what was said  if you want integer powers of two  then 1  lt  lt  x  or 1L  lt  lt  x  is a faster way to calculate  2x than Math pow 2 x  or a multiplication loop  and is guaranteed to give you an int  or long  result   It only uses the lowest 5  or 6  bits of x  i e  x  amp  31  or x  amp  63    though  shifting between 0 and 31  or 63  bits
