We use .NET Web Services--both non-WCF and WCF, though the overwhelming majority is non-WCF, for legacy reasons--pretty heavily, and as I was testing something in Fiddler, I noticed that the response body size was pretty large.

I've been poring through .NET disassemblies and the GCC source code, but can't seem to find anywhere the actual implementation of sin() and other math functions... they always seem to be referencing something else.
