DISTANCE macro

The DISTANCE macro is available in IBM® Campaign and IBM® Interact.

Syntax

DISTANCE(lat1, long1, lat2, long2[, UNIT_OF_MEASURE][, PRECISION])

Parameters

lat1

The latitude of the first point, as a decimal value.

long1

The longitude of the first point, as a decimal value.

lat2

The latitude of the second point, as a decimal value.

long2

The longitude of the second point, as a decimal value.

UNIT_OF_MEASURE

An optional parameter indicating the unit of measure for the returned distance. Values are MILES or KILOMETERS. If you omit this parameter, MILES is the default.

PRECISION

An optional parameter indicating the level of precision following the decimal point for the returned distance. If you specify a precision value, the returned distance is truncated to the number of decimal places you specify. The maximum value is 5. If you omit this value, the number of decimal places is not truncated.

Description

DISTANCE calculates the distance between two points. Latitude and longitude are expected to be in decimal units. Always use a comma and a space to separate numeric values. This is necessary to accommodate languages that use a comma as a decimal separator, as shown in the second example below.

Examples

DISTANCE (18.529747, 73.839798, 18.533511, 73.8777995, MILES, 2) returns the value 2.50 Miles.

DISTANCE (18,529747, 73,839798, 18,533511, 73,8777995, KILOMETERS, 1) returns the value 4,0 kilometers.
