Subject: BigDecimal with Float comparision bug.

Hello,

I have noticed that BigDecimal may fail in many cases when you try to
compare it with float:

Float:
>> BigDecimal.new("25.0") == 25.0
=> false
Decimal:

>> BigDecimal.new("25.0") == 25  
=> true


>> (1..1000).select { |d| BigDecimal.new("#{d}.0") != d.to_f }.size
=> 414

So 41.4% such comparisions are false!!!

What do you think about it?

Regards
