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.
