Get_X
Geometric functions Get_X
- get_x(point data item)
get_x(point data item) results in a data item with the X coordinates of the argument point data item.
Since GeoDMS 20.22.0 a null point results in a null x-coordinate. Before, a null point of an integer point type (ipoint, spoint, wpoint, upoint) resulted in a number, -2147483648 for an ipoint; a null float point already resulted in null.
