How then you can provide 10 valid digits of results, concerning deliberate rounding of pi to 3.14 and available accuracy estimation of G ? As a homework, you may calculate the error propagation from inputs to result. BTW, 149597870700 m is not estimation, but definition of AU. -- Poutnik ( the Czech word for a wanderer ) Knowledge makes great men humble, but small men arrogant.
