-From time to time I wonder why there is no BigDecimal
initializer taking a Float argument. There seems to be a
point as Float values aren't unambiguous and you have to
explicitly mention which one you mean of

  "%f" % 1.8       #  => "1.800000"
  "%32.24f" % 1.8  #  => "      1.800000000000000044408921"

So I'd rather say it's disencouraged to convert Float to
BigDecimal.
