DISTANCE(point1,point2)

• Where 'point1' is any point with coordinates[x1,y1] and
• 'point2' is any point with coordinates[x2,y2]

DISTANCE() calculates the distance between two points.

Description

DISTANCE(point1,point2)

DISTANCE([2,3],[6,7]) returns 5.656854249492381

• This function returns the distance between two points using the following formula -

DISTANCE = SQRT( (x2-x1)^2  + (y2-y1)^2 )

        = SQRT((6-2)^2 + (7-3)^2)
        = SQRT(32)
        = 5.656854249492381

• If any of the co-ordinates (x1,y1,x2,y2) is non-numeric, Calci returns an error message.
• If the function is not available, then load the geometry by using 'load geometry' command.
