Subject: [ruby-core:59376] [ruby-trunk - Bug #9316] BigDecimal division in	Ruby 2.1


Issue #9316 has been updated by dmarkow (Dylan Markow).


=begin
Also, it appears to only happen when the right side number is less than 1:

 >> BigDecimal.new("1472.0") / BigDecimal.new("0.99")
 1487.0 # Should be 1486.868686869
 >> BigDecimal.new("1472.0") / BigDecimal.new("1.0")
 1472.0 # Correct
 >> BigDecimal.new("1472.0") / BigDecimal.new("1.01")
 1457.425742574257425743 # Correct

=begin
When updating an app to Ruby 2.1, and I ran into the following difference between ruby 2.0.0-p353 and ruby 2.1.0 when dividing two BigDecimals:

((*Ruby 2.0.0p353:*))
 2.0.0p353 :002 > (BigDecimal.new("1472.0") / BigDecimal.new("0.99")).to_f
  => 1486.868686869

((*Ruby 2.1.0p0:*))
 2.1.0p0 :006 > (BigDecimal.new("1472.0") / BigDecimal.new("0.99")).to_f
  => 1487.0
=end
