OK, matches ROOT.
julia> using StatsBase
julia> h1 = Hist1D([0.5,1.5,1.5,2.5], Weights(ones(4)), 0:3);
julia> h2 = Hist1D([1.5,2.5,2.5], Weights(ones(3)), 0:3);

h1 = ROOT.TH1F("h1", "", 3, 0, 3); h1.Sumw2()
h2 = ROOT.TH1F("h2", "", 3, 0, 3); h2.Sumw2()
for x in [0.5,1.5,1.5,2.5]: h1.Fill(x)
for x in [1.5,2.5,2.5]: h2.Fill(x)
h1.Divide(h2)
