I have updated the code to use %.15g which appears to give reasonable values
at different value sizes.  I don't like using something like %.15f because
it introduces many bogus digits of accurancy for coordinate systems with
large values like UTM.  But %.15g seems to mean 15 digits of accuracy rather
than 15 decimal places.

The GMU server is now working properly for me.
