Is the BigDecimal class broken? It seems like the following should never, ever occur: Note that a.to_f != a.to_s.to_f
a.class => BigDecimal
a.to_f => 18658.1072928
a.to_s => "10865.81072928"
b.class => BigDecimal
b.to_f => 10000.0
b.to_s => "10000.0"
(a - b).to_f => 865.81072928
a.to_f - b.to_f => 8658.1072928
Any ideas as to what might be going wrong?
