LatLong class

Immutable geographic coordinate representing a point on Earth's surface.

This class stores latitude and longitude values in decimal degrees using the WGS84 coordinate system. It provides conversion utilities for microdegrees (degrees * 10^6) and supports parsing from various string formats.

Key features:

  • Immutable design for thread safety
  • WGS84 coordinate system compliance
  • Microdegree conversion for high-precision storage
  • String parsing with multiple separator support
  • Efficient equality comparison and hashing
