[OSRM-talk] Geometry Polyline Coordinates multiplied by 10

Hey Bryan,

  The simplest thing to might be to just add "compression=false" to your /viaroute request.  That'll give you back a plain JSON array of coordinates, rather than in encoded form.

I've noticed that, when I use a standard decoder to decode these polylines (i.e. Python's polyline package), the lat/lon coordinates I get are multiplied by a factor of 10. Googling around, I found that this is due to OSRM producing coordinates at a higher precision; is there a way for me to decode these without writing my own decoder, or digging into an existing one? Is it safe for me to simply divide the decoded coordinates by 10?
