Bug #5098: bigdecimal/util.rb で定義される to_d メソッドによる型変換と、BigDecimal 関数による型変換が整合していない

• Status: Closed
• Assignee: mrkn (Kenta Murata)
• Target version: 1.9.3
• ruby -v: ruby 1.9.4dev (2011-07-17 trunk 32564) [x86_64-darwin10.8.0]

[mrkn (Kenta Murata)]

BigDecimal() および BigDecimal#coerce との関係より、以下のように修正が必要。

• Float#to_d はオプショナルな精度を受け付けるように変更し、精度が省略された場合は Float::DIG が指定されたものとする。
• Rational#to_d は精度を必須とする。
• Integer#to_d を追加する。
