[Xml-compile] $_[0] + 0.0 for sloppy floats

[Patrick Powell]

Floats are evil.  This discussion brings back horrible memories of 
1960's and dealing with multiple hardware architectures and floating 
point formats.  IEEE 754 cleared a lot of this up but as we can see 
there are still *())(*& issues with textual representation.

Ummm... and look at JSON and 'true' and 'false'.
