Research direction

Start by reproducing the reported example at the HypergeometricFunctions.pFq entry point with TaylorSeries' TaylorN values and inspect where the AbstractFloat conversion is triggered. Done means the shown pFq call works when HypergeometricFunctions and TaylorSeries are used together, with coverage for this compatibility case.

Description

I tried to use HypergeometricFunctions and TaylorSeries at the same time as follows.

using HypergeometricFunctions
using Plots
using TaylorSeries
x = set_variables("x", order=100)[1];
Base.isless(y::Number, x::TaylorN) = isless(y, x.coeffs[1].coeffs[1])
Base.log1p(x::TaylorN) = log(1+x)
Base.eps(::Type{TaylorN{T}}) where T = eps(T)
Base.isless(x::TaylorN, y::Number) = isless(x.coeffs[1].coeffs[1], y)
HypergeometricFunctions.pFq((2.0,),(5.0,),x)

However, I got the error:
ERROR: MethodError: no method matching AbstractFloat(::TaylorN{Float64})

Closest candidates are:
(::Type{T})(::T) where T<:Number
@ Core boot.jl:792
(::Type{T})(::AbstractChar) where T<:Union{AbstractChar, Number}
@ Base char.jl:50
(::Type{T})(::Base.TwicePrecision) where T<:Number
@ Base twiceprecision.jl:266
