  By doing that you will be slowing down the code.

  This: "int i = some_double;" is equivalent to this:
"int i = int(some_double);".
  However, you are adding an additional 'floor()' call which will
slow down the conversion needlessly.
  It will also probably give a different result with negative numbers.
