TheLatLng64 is a 64-bit structure that compactly contains latitude and longitude data with an accuracy of ±2.8 mm.This format is great for geographic databases. Occupies half the space of traditional solutionsand provides accuracy sufficient for the vast majority of applications.

• The structure occupies 64 bits of memory and uses them to the maximum.
• In the populated part of the Earth, the accuracy is no worse than ±2.8 mm.
• In the polar regions of the Earth, the accuracy is no worse than ±5.6 mm.
• The restored latitude and longitude values have a neat decimal form.
  
  

• TheFloat32 pair has different precision depending on the location.Step up to 1.7 m is unacceptable for most applications.
• TheFloat64 pair is the traditional solution.But it takes up a huge 128 bits and gives meaningless sub-nanometer precision.
• TheInt32 pair can give uniform accuracy of ±5.6 mm. It gives four times fewer values ​​per area thanLatLng64.
