I tried next example on Maxima,
(C1) fpprec : 50;
(D1) 50
(C2)
float(120938498304852938452489509485245834985034541)-bfloat(1209384983048529
38452489509485245834985034541);
Warning: Float to bigfloat conversion of 1.2093849830485294E44
(D2) 3.772935106511773832671833299B27
I made sure of the problem in converting big number.
In addition, on common-lisp, I did the function (rational).
(rational 2.718)
5700059/2097152
But 5700059/2097152 isn't 2.718, I hope 2718/1000 or 1359/5000(reduce a
fraction). I think now we will face these problems of converting big
numbers, ex. in case of investigating the number of molecule, atom etc..
