Thanks, I didn't know that Ratio constructor was available via GHC.FLoat.
I have done a test using the :% operator, instead of the % operator,
but, the program run slower!
About 29 seconds, against 20 seconds of the previous version (and 10
seconds of the Python version).
I was expecting to obtain an execution time of about 6 seconds...
