410 :: 1/0 returns inf, expected?

  echo 1/0 # this is inf
  Run

  This is even inf when both values are read at runtime. Nimrod has EFloatDivByZero, but

  
  echo 1.0/0.0
  Run

  returns inf too. Should not both rise an exception?

  / always is a floating point division. EFloatDivByZero is only concerned with integer division (div).

  With --infChecks:on I get (at runtime): Error: unhandled exception: FPU operation caused an overflow [EFloatOverflow]

  Ok, that makes sense. Thanks for your answer.
