It sort of helps in the sense that the hint about specifying the types is
useful.
I could not apply the solution directly because it lead to another very
surprising (to me) quirk of FriCAS: lack of a basic form of referential
transparency between variables and literals. Namely if you assign a

Does the following help?
The idea is that you specify the type so that the result is not
Expression(Float) (and must later be converted to (Double)Float, but
rather an element of DoubleFloat.
I got a problem trying to plot a function that uses the erf funtion. It
seems that the reason was that erf is sometimes left unevaluated by FriCAS
even in expressions that only involve erf and numbers.
To replicate one can define the expression like
