  What nonsense!  You have only so many bits of precision.  When a result
  (eventually) needs more than that, instead of losing the most significant
  bits, as in C-style "integer" arithmetic, you lose the least significant
  bits, which generally goes undetected.

  Which is a rational.

  In a fight against something, the fight has value, victory has none.
  In a fight for something, the fight is a loss, victory merely relief.
