In fact, 1.9.2 doesn't have it eit= her:

1.8.7 :001 > require 'bigdecimal'

1.8.7 :002 > require 'bigdec= imal/util'

1.8.7 :003 >= 25.to_d

NoMethodError: undefined method `to_d' for 25:Fixnum=

So, can we add = this to stdlib of 1.8.7 and 1.9.2?=C2=A0

I'm running Ruby 1.9.3 on Windows XP. According to the docs[1], #to_d is defined for BigDecimal, Float, Rational, String, and Integer (which
is a superclass of Fixnum and Bignum).
