my friend found another cursed coordinate format: fitness tracker storing latitude as signed integers, 0-2³², where 0 is the prime meridian and 2³²-1 is... -1/(2³²) (so back at Greenwich)

counting up as you go east or north, basically. the formula to convert back to decimal is apparently n / ( 2³² / 360 ).

but it's a signed integer, so you can go forwards or backwards around the globe, so in theory every point on the globe could be marked by 4 distinct sets of coordinates?

i can imagine a reason to do this - if I'm running around Wrangel Island, then the tracker can keep it's head on and not think I'm teleporting all the way around the world. but it didn't actually do that! it caps the values in software to -90/90 or -180/180! so why have this insane format‽

gotta wonder who comes up with this stuff. don't make me tap the sign, garmin
