Is Symbolics.jl incompatible with plotting, cannot convert Num to subtype, MethodError: no method matching Float64(::Num)

[greatpet]

Here’s another solution with minimal change of the original code. Just use

plot(Symbolics.value ∘ f_subs)

and a plot shows up. This is because the function Symbolics.value converts a number of the Num type (defined by Symbolics) to Julia’s native number type.
