Comment:

 I just figured out how to fix that. that's why I re-open this ticket.
 This idea came to me when calculating numbers with my HP Prime
 calculator.\\
 as I said above, GHC calculates well.
 it's a matter of displaying a number.
 we can give ourselves a limit in the display of the number which will
 be for example 5 digits of precision after the decimal point. in a new
 request ticket I talked about 11 precision digits in the display.\\
 I specify for those who have not understood anything yet that it is a
 precision in the display and not in the internal calculation. \\
 5 digits may seem sufficient considering that GHC is more used in the
 functional part more than in the intensive mathematical calculation.
 example:\\
 if the number is:{{{79.999999}}} he can become {{{80}}}
