When representing latitude and longitude in degrees, minutes and seconds, with
- -180 <= D <= 180 (or -90 and 90)
- 0 <= M < 60 (0 if D is at an extreme)
- 0 <= S < 60 (0 if D is at an extreme)
How can values between -1 degree and 0 degrees be represented? Since there is no distinction between 0 and -0, there is no way to distinguish between 0:12:34 and -0:12:34.
Is this just a limitation of this kind of representation, or is there some convention that allows it to cover this gap?
