A lot of sophisticated applications require fractions. This is not native to UPLC and hence not easy to represent in python

I want to implement `//` for my own types. The return type would subtype `Real` and it'd also overload `numerator` and `denominator`, but it wouldn't subtype `Rational`. Would that be allowed?

I was trying to integrate the following expression:
Integral(simplify(sqrt(2+t**(-2)+t**2)),t).doit()
but it failed because the expression was not correctly simplified. The integrand is sim…

It might be a good sanity check to try use our code to recover results in the case of the first number field: $F = \mathbb{Q}$. Currently our code seems to only work for real quadratic fields, so tryi…

Reported by email by Rene Marczinzik. This calculation reports that `U` is commutative, while it is not:
```
gap> G:=QuaternionGroup(8);
gap> R:=GroupRing(Rationals,G);

Sharebill should support:
- Decimal notation
- Basic algebra (+, -, * and /)
- Precise calculations with big rationals (not necessarily arbitrarily big rationals, but I think `number` is too smal…

We currently use double for clock valuations, which already caused some bugs, e.g., #88.
We might want to use Rationals altogether. We should check again whether this would make sense.

bc.. Hi,
Using, sympy 0.6.3, I noticed the following :
> > > s.Real('2.5').is_rational
> > > (sympy.Integer(5)/2).is_rational
> > > True
> > > s.Real('2.5') == sympy.Integer(5)/2
> > > True
I think…

`std.rational.Rational` currently implements `opCast` for both integer and floating-point types, and `toRational` to enable arbitrary floating-point values to be converted to their nearest rational (w…

Hi !
In this example I have a simple constant folding rule:
```egglog
(datatype Math
(Num i64)
(Add Math Math)
)
(rewrite (Add (Num x) (Num y)) (Num (+ x y)))
(let expr (Add (Num 92233…
