Hi Patrick,
Rounding off is pretty easy:
Code:
numbers = [179.3428955078125, -69.40995025634766, 88.83070373535156]
for i, number in enumerate(numbers):
numbers[i] = round(number,1)
print numbers
However, I don't know if that will result in smoother tracking, because the coordinates will not be on a continuum. However, you can always try

.
Another option to smooth your tracking would be to (re)calibrate your tracker, or to decrease the distance from your tracker to your tracking device. Good luck!
