no method matching `div(::PolyForm, ::Rational)` #449

Open t0rny opened 2 years ago

t0rny commented 2 years ago 
using SymbolicUtils
@syms x
poly = PolyForm(x^2)
div(poly, 4//3)

yields the following error. 

ERROR: MethodError: no method matching div(::PolyForm{Number, Nothing}, ::Rational{Int64}, ::RoundingMode{:ToZero})

Is PolyForm not expected to be divided by Rationals?
