Use helper function to write decimal numbers

Browse source 
Never ever use '%f' to write floating point data to a file. The stupid
locale handling creates useless comma-infested output in some locales.
Instead use one of our clever helper functions to do the right thing.

Original patch by Gehad, modified by Linus to be a little more generic.
