Negative Longitude corresponds to Longitude in the WESTERN Hemisphere.
Positive Longitude corresponds to Longitude in the EASTERN Hemisphere.
Longitude Calculation Example:
24-bit longitude: 0xBFF46B (Hexadecimal)
This number converted to decimal (base 10) is: 12,579,947.
12,579,947 * (180.0 / 223) = 269.936378
Since this result is greater than 180 degrees, subtract 360 degrees from the result to create the correct signed representation.
69.936378 degrees – 360 degrees = -90.063622 degrees = 90.063622 degrees WEST
