+## Usage
+
+```javascript
+var enum2str = require( '@stdlib/ml/base/cluster/kmeans/metric-enum2str' );
+```
+
+#### enum2str( value )
+
+Returns the KMeans distance metric string associated with a KMeans distance metric enumeration constant.
+
+```javascript
+var str2enum = require( '@stdlib/ml/base/cluster/kmeans/metric-str2enum' );
+
+var v = str2enum( 'sqeuclidean' );
+// returns <number>
+
+var s = enum2str( v );
+// returns 'sqeuclidean'
+```
+
