Hi,
I'm using an Orocos componnent in a highly accurate application and I
discovered that orocos marshalling.writesProperties() is no giving enough
digits when writing double(s). Right now, it's giving me only 7 digits and I
would like to use 16 digits.
Can someone help me?
marshalling()->writeProperties need more precision

I posted on this very topic in the last few weeks, and outlined the
fix required to do this. Search the archives should bring it right up
- it was a one file change and a recompile of RTT. There have been
other posts recently on this topic too ...

The fundamental solution is to make the property system rely on the
type system fully, such that a user can define his own 'high
precision' data type and influence marshalling by using this new type
or override the marshalling of doubles (that's for all doubles then)
