point_yx

Geometric functions point_yx function

syntax

• point_yx(Y coordinate, X coordinate, optional coordinate unit)

definition

point(Y coordinate, X coordinate, optional coordinate unit) results in a two-dimensional point data item.

conditions

1. The value type of the Y coordinate and X coordinate data items must match with each other and with the coordinate unit:
   • uint16 data items for wpoint units;
   • int16 data items for spoint units;
   • uint32 data items for upoint units;
   • int32 data items for ipoint units;
   • float32 data items for fpoint units;
   • float64 data items for dpoint units.
2. The domain units of the Y coordinate, X coordinate and resulting data items must match.
