      Type:  defect    |      Status:  closed               
  Priority:  major     |   Milestone:

Resolution:  invalid   |    Keywords:  arithmetic operations

Changes (by ross):

  * resolution:  => invalid
  * status:  new => closed

Comment:

 This is normal behaviour for floating point types in any language: being
 fixed size binary formats, they can represent decimal fractions only
 approximately.  For operations on exact fractions, Haskell provides
 `Rational`.
