Backport #7176: Rational can't be coerced into BigDecimal (TypeError)

• Status: Closed
• Assignee: usa (Usaku NAKAMURA)

[aptinio (Aaron Tinio)]

Rational + BigDecimal makes a BigDecimal as follows:

$ ruby -rbigdecimal -e "puts Rational(1) + BigDecimal.new('1')"
0.2E1

But BigDecimal + Rationl raises a TypeError as follows:

$ ruby -rbigdecimal -e "puts BigDecimal.new('1') + Rational(1)"
-e:1:in +': Rational can't be coerced into BigDecimal (TypeError) from -e:1:in '

This is also encountered in ruby 1.9.3p286 (2012-10-12 revision 37165) [x86_64-linux]
