Map and Table Calculation

CRDX( ) function

Returns the X component of an (X,Y) coordinate.

Syntax

CRDX(Coordinate)

Input

Coordinate	is an (X,Y) coordinate
Domain type:	a coordinate system

Output

CRDX returns:	a value
Domain:	system domain Value

Note:

This function is mainly designed to store the resulting X-coordinate of a coordinate calculation. The output can be used as input in other calculations.

Tips:

This function may be handy to use in DDE applications.
When the definition symbol = is used, a dependent output column is created; when the assignment symbol := is used, the dependency link is immediately broken after the output column has been calculated.

Usable in

TabCalc, Simple calculators

Examples

Pocket line calculator examples:

? CRDX(COORD(10,20))	returns the X component of coordinate (10, 20), i.e. 10
? CRDX(PNTCRD(Rainfall,"PROMIC"))	returns the X component of the coordinate of rainfall station PROMIC in point map Rainfall, e.g. 802613.000
? CRDX(MAPCRD(DEM,120,150))	returns the X coordinate of raster map DEM at row 120 and column 150, e.g. 798470

TabCalc examples:

OutCol = CRDX(Coordinate)
