saving with higher precision

I am working with HMMs for chord recognition and the limited precision of the save restore utility gave me some headaches.
It would be nice to have an option for saving floating point numbers with higher precision.
This could easily be done with std::setprecision(number) in the save restore utility for the file output stream.

Hello there,

The correct solution to this is to store the transition matrix values and the emission probability values in binary instead of as a string, but for now I've done what you suggested and added a std::setprecision(15) to the relevant calls. I've attached a patch you can apply (or modify if 15 isn't enough). The reason I didn't go through and start storing HMM values in binary format is that the SaveRestoreUtility is going through a bit of overhaul right now, so I don't want to make an svn merging nightmare for the guy working on it. If you're using svn trunk already, I merged these changes in in r16136.

Definitely in the future, though, binary saves is the right way to go. Feel free to reopen the ticket if this doesn't solve the problem.

Thanks,

Ryan
