[Haskell-beginners] This code does not work : conversion error

[David McBride]

You just have a few problems.  Where should be lowercase.  The single
quotes should be backticks "`".  You may have some indentation issues.  And
lastly, you have some problems with e and f

   e = round (log $ fromIntegral n)
   f = round (log 2)

Otherwise it seems fine.
