Cannot compare list of polynomials because of missing `rtoldefault` #289

Open kbarros opened 6 months ago

kbarros commented 6 months ago

using DynamicPolynomials
@polyvar x
a = [2x, x^2]

# Fine to compare individual elements
@assert a[1] ≈ a[1] && a[2] == a[2]

# ERROR: MethodError: no method matching rtoldefault(...) 
a ≈ a

I guess we should add Base.rtoldefault(::AbstractMonomialLike) = MA.Zero() in MultivariatePolynomials
