According to the docs, this should be achievable as you suggest, using:

in "OK:%f,%3.1<xor>"

or whatever value and checksum conversion type you need.
I've looked at the code and can't see why a precision wouldn't work.

What is the error message, exactly?
Have you tried setting streamDebug to 1 (you should be able to do this from the console without rebuilding) and seeing if the copious debugging output helps you to see what's going on?
