Did you check the link given in the answer where I was replying to which uses it there? I just copied it. Here is the link again

Symbolic sqrt(2) and sin(pi)

I asked this as a genuine question but looking at Symbolics.jl more closely I get the impression that the answer is that there is no way to do this even for sqrt(2). If that’s the case then this is something very different from other CAS… Am I misunderstanding this? How can sqrt(2) be represented exactly?

someone used SymbolicValue there. I have no idea where it came from.
