  This is so common a request that IEEE 754 has support for not causing an
  overflow or underflow, but instead return 0 and the largest possible
  value (as opposed to an internal "infinity" value).  This is not directly
  supported by the Common Lisp standard, but you should find some support
  for it in your implementation, or, if not, you should request it.
  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.
