>From the Language Reference:

  The / (division) and // (floor division) operators yield the quotient
  of their arguments. The numeric arguments are first converted to a
  common type. Plain or long integer division yields an integer of the
  same type; the result is that of mathematical division with the
  `floor' function applied to the result.

So, first the arguments are converted to a common type, in this case
float. Then the division is made. Then the 'floor' function is applied.
Result: 3.0.

So yes, it's intentional.
