+#### TypedArrayFE.prototype.fill( value\[, start\[, end]] )
+
+Returns a modified typed array filled with a fill value.
+
+```javascript
+var Float64ArrayFE = fixedEndianFactory( 'float64' );
+
+var arr = new Float64ArrayFE( 'little-endian', [ 1.0, 2.0, 3.0 ] );
+
+// Set all elements to the same value:
+arr.fill( 6.0 );
+
+var z = arr.get( 0 );
+// returns 6.0
+
+z = arr.get( 1 );
+// returns 6.0
+
+z = arr.get( 2 );
+// returns 6.0
+
+// Fill all elements starting from the second element:
+arr.fill( 7.0, 1 );
+
+z = arr.get( 1 );
+// returns 7.0
+
+z = arr.get( 2 );
+// returns 7.0
+
+// Fill all elements from first element until the second-to-last element:
+arr.fill( 8.0, 0, 2 );
+
+z = arr.get( 0 );
+// returns 8.0
+
+z = arr.get( 1 );
+// returns 8.0
+```
+
+When a `start` and/or `end` index is negative, the respective index is determined relative to the last array element.
+
+```javascript
+var Float64ArrayFE = fixedEndianFactory( 'float64' );
+
+var arr = new Float64ArrayFE( 'little-endian', [ 1.0, 2.0, 3.0 ] );
+
+// Set all array elements, except the last element, to the same value:
+arr.fill( 6.0, 0, -1 );
+
+var z = arr.get( 0 );
+// returns 6.0
+
+z = arr.get( arr.length - 1 );
+// returns 3.0
+```
+
 ## Notes
 
 -   A returned constructor supports the following byte orders:
