Comment(by ohshima):

 You would limit the number of digits at somewhere but I would say it
 should not be like 9 or such.  Very the least, it should be possible to
 display the digits that double precision floating point math guarantees,
 and for integers, you could go 100 or such, no?

 BTW, what is the precision it uses for storing data and displaying?  If I
 type "e*e*e", I get 20.0955369.  Then I type "*e", the last result is used
 and I get "54.5981449".  However, if I type "e*e*e*e", I get "54.5981500".
 Even if you display the result with truncation, the internal value could
 be more precise?  Or, at least these two should return the same result?
