I see a little thing I no understand, sometime there is decimal
instead of integer.

I give example in attachement. Even I try mani things it is no change.

It is not important you know.

This gets rid of the unwanted real:

Code:


EXPORT TRYG()
BEGIN 
 LOCAL LL={5/9,7/4,6/11};
 LOCAL DD:=1/gcd(exact(LL));
 LOCAL NN:=LL*DD;
 
 RETURN {approx(DD),NN};// numerators or
 RETURN {approx(DD),exact(NN/DD)}; // fractions
END;

But the fractions are not nice: x/1/1/396 instead of x/396.
