Comparing non-matching Floats gives `undefined method []' for 0.0:Float` within SuperDiff

[simonrentzke]

Hi, I've noticed some weird behaviour when floats are compared and they do not match

Example code:

require "rails_helper"

describe "BadMatcher", type: :feature do
  it "should not give NoMethodError" do
    expect(0.0).to eq(0.15)
  end
end

Stack trace looks like this:

Failures:

  1) BadMatcher should not give NoMethodError
     Failure/Error: expect(0.0).to eq(0.15)

     NoMethodError:
       undefined method `[]' for 0.0:Float

ah, apologies, this looks like a duplicate of #136
