        let numbersAfterCommaAccuracy: Double = 4

// Tests:

let location1 = CLLocationCoordinate2D(latitude: 55.11925634599045, longitude: 36.60896733330129)
let location2 = CLLocationCoordinate2D(latitude: 55.11925632599047, longitude: 36.608967333301294)
let location3 = CLLocationCoordinate2D(latitude: 55.11925, longitude: 36.60896)
let location4 = CLLocationCoordinate2D(latitude: 55.11926, longitude: 36.60897)
let location5 = CLLocationCoordinate2D(latitude: 0.0, longitude: 0.0)

print(location1 == location2) // true
print(location1 == location3) // true
print(location1 == location4) // false
print(location1 == location5) // false
