Dan, could you provide some more specifics here? Altitude in meters, feet, or furlongs? Against what reference? Number of significant digits you expect? Latitude and longitude are in decimal degrees? An example would also help.

Thank you for suggestions

I like test #7. Although doing it the "right" way, I seem to get decimal precision on the negative values which caused it to fail the test suite.

Fixed tests with negative values and rescored solutions!

the expected level of precision of the responses seems a bit unreasonable (<1 nanometer?), perhaps you could allow +-1% error in the returned altitude responses?

Modified tolerance of the answers.
