Bug #4894: incorrect conversions from BigDecimal to Float
http://redmine.ruby-lang.org/issues/4894

Author: Cannon Matthews
Status: Rejected
Priority: Normal
Assignee: Kenta Murata
Category: lib
Target version: Ruby 1.8.7
ruby -v: ruby 1.8.7 (2009-06-08 patchlevel 173) [x86_64-linux]


=begin
I am working with BigDecimals, and was previously using floats. I came across this strange bug where when converting from BigDecimal down to float, zeros in the middle of the number get removed.

 require 'bigdecimal' #=> true
 require 'bigdecimal/util' #=> true

 BigDecimal.new("40.08").to_f #=> 40.8

which are obviously 2 very different numbers. This happens with implicit converisons too:

 BigDecimal.new("48.08") - 40.00 #=> 8.8
 

if this has already been fixed, my apologies.
=end
