#2395
Use simple round-trip format for doubles because G17 prints some strange numbers (20.22 to 20.219999999999999999).
Some accuracy can still be lost on 64bit machines, but should be very rare and minimal.
double.MaxValue can still be parsed correctly, solving the problem of invalid value for the GUI.
