mm, i already use that package, and works very fine, but it feels it can be more easy adding this to octave core, anyway, thx for the help.
As a note to can use the symbolic package with normal numbers:

var=sym(expresion)
ex.
matrix=sym([1,2;3,4])

Cya.

Thanks for your feature request. This actually already exists, it's called the symbolic package for Octave. Using the functions in the symbolic package gives you access to algebraic manipulation and to variable-precision calculations.

This is not going to be a part of core Octave, though, Octave is a numerical tool by nature. But please do use the symbolic package to do what you are looking for:

Hi, as say the title i'm requesting this feature, the idea is calc avoinig decimals or calc with the fraction, basically if i write 1/3 don't aprox to 0.33333 (or when octave get this type of calcs) and can enable it globally, i think it can be very useful for precision work. Actually with the aprox (ex 1/3 -> 0.3333333333333) some calcs have problems if you need a extremely precise calcs.

Cya.
