Hi Andrew,
I realised later that we can use Tcl_SetObjResult() instead of
Tcl_SetResult() without migrating to the full Tcl_Obj interface style
yet. That will allow us to return double precision floating point
results without the string conversion. But fixing that issue you
mentioned should take priority. What is it?
Regards,
Arjen
