Basic question on Julia symbolic. How to keep exp(1) as is and not convert it to a floating point number?

Do you know of a different symbolic Julia integrator than the above? It is the only one I found when googling.

That’s the only one right now.

@Nasser

Well, it says " hybrid symbolic/numerical integration package that works on the Julia Symbolics expressions."

Yes, and it’s symbolic-numeric, as in, it uses numerical methods to solve for the symbolic equation. So it needs to numerically evaluate, and it cannot keep a closed representation of transcendentals (nor algebraic variables, I think it can do rationals in some sense though?)
