In GPS data, I store altitude to the nearest metre in an int16_t, and
altitude and longitude in degrees in 32-bit fixed-point types.
Although longitude needs one more bit than latitude I tend to use the
same type for both, so my 2d algorithms are homogeneous. But anything
that also involves altitude needs to be heterogeneous.
