## Detailed Description

Tracking distance contains two types of distances - raw and display. Raw distance is always in meters (fixed units). Display distance is in LinearUnit.

## Member Function Documentation

`[override virtual] `

TrackingDistance::~TrackingDistance()

Destructor.

### QString TrackingDistance::displayText() const

Returns formatted and rounded distance, ready for displaying.

The distance is expressed in LinearUnit. Use this property to have consistent distances/units with voice guidances. The following rules are used for rounding and formatting:

IMPERIAL - 0 -> 50' => Round to increments of 10' (e.g. "10", "20", "30", "40") - 50' -> 0.1 mi (528') => Round to increments of 50' (e.g. "50", "100", "150", etc.) - 0.1 -> 1.0 mi => Round to decimal tenths of a mile (e.g "0.1", "0.2", "0.3", etc.) - 1.0 mi -> 10 mi => Round to half mile (e.g. "1.0", "1.5", "2.0", etc.) - 10+ mi => Round to mile (e.g. "10", "11", "12", etc.)

METRIC - 0 -> 50 m => Round to increments of 10 m (e.g. "10", "20", "30", "40") - 50 m -> 500 m => Round to increments of 50 m (e.g. "50", "100", "150", etc.) - 500 m -> 10 km => Round to half km (e.g. "1.0", "1.5", "2.0", etc.) - 10+ km => Round to whole km (e.g. "10", "11", "12", etc.)

### Esri::ArcGISRuntime::LinearUnit TrackingDistance::displayTextUnits() const

Returns the units used in the displayText which vary base on distance from maneuver/destination.

### double TrackingDistance::distance() const

Returns raw distance in meters.
