これを眺めて、推移律が成り立たないんじゃないかなぁ、と思ったので、
ちょっと試してみるとやはり反例を作れました。

% ./ruby -rbigdecimal -ve '
f1 = 131.2
f2 = 131.20000000000002
b = BigDecimal("131.2")
p f1 == b
p b == f2
p f1 == f2
'
ruby 2.1.0dev (2013-12-08 trunk 44077) [x86_64-linux]
true
true
false

このコミットで始まった話ではないようですが。

推移律が成り立たないというのは同値関係ではないということで、
気にする人はいるような気がします。
どのくらいの人が気にするかはわかりませんが。
