What?

Right now the calculator can't handle any fractions or decimals, the plan is to implement it so that it can :).

How?

Well, there are two aproaches i want to have, first one would be to just allow floating pointers, we already have NODE_INTEGER for that so adding NODE_FLOATING or something like that and adding it to the union as well as adapting the lexer would be really easy. But, i want another approach too.

Instead of taking a floating point as literally that, we could have a Fraction type that stores the denominator and numerator, it would even have an algorithm for reducing itself for its minimal expression, handle 0 cases, could even extend to work as the division operator.

I would like to make the default to be use fractions instead of floating points so it will need to have the option to change that
