title: Round up double to long in Java
body: <p>Is there a method in java which round up double to Long in java?</p>
  
  <p>eg.
  double d=2394867326.23;
  I need to round this up to 2394867327. The result is not an integer, so I think cannot use Math.ceil.</p>
  
  <p>Do we have a method in java which return the Long instead of int?</p>
