Precision in MP3 decoder

In addition to the discussion at
http://www.hydrogenaudio.org/forums/lofive...php/t17132.html

I am wondering if the 32-bit floating-point precision in the decoder really satisfis everybody? I know a lot 16b or 32b fixed-point hardware decoders in applications. How do they perform?

And also I found a website talking about MP3 standard compliance
http://www.underbit.com/resources/mpeg/audio/compliance/

where Lame 3.86 didn't pass the test  It seems that Lame 3.86 and later versions all use 64b float already .... Anyone can explain this a little bit.

Thanks a lot!
