Precision

Open MtnBiker opened this issue 6 years ago • 1 comments

Not very important but would be nice to have fewer "significant" figures. Maybe six after the coordinates which is 100mm which is certainly better than any iPhone GPS, and zero or one significant figure for elevation. 1m or 0.1m again more than the iPhone is capable of.

Did you mean the recorded coordinates of the GPX file?

Higher floating point precision was actually added in v1.7.0 of this app, as part of a component of the app, CoreGPX 0.7.4 which contains such a 'feature'.

This was achieved as I thought that the use of Double (at least 15 decimals) over Float (at least 6 decimals), shouldn't hurt much, and would allow a more true representation of what the device reports as of recording, even if it's minor.

If indeed, it is this 'feature' that bothers, do elaborate, and I may implement a way of choosing precision.
