Hi there,

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

I was wondering if this is intentional, a regression or I'm just doing
something wrong. Should I open an issue?

Cheers!
Andre
