+
+## Usage
+
+```javascript
+var xor = require( '@stdlib/number/uint64/base/xor' );
+```
+
+#### xor( a, b )
+
+Computes the bitwise XOR of two 64-bit unsigned integers.
+
+```javascript
+var Uint64 = require( '@stdlib/number/uint64/ctor' );
+
+var a = new Uint64( 5 );
+var b = new Uint64( 15 );
+
+var v = xor( a, b );
+// returns <Uint64>[ 10n ]
+```
+
+#### xor.assign( ah, al, bh, bl, out, stride, offset )
+
+Computes the bitwise XOR of two 64-bit unsigned integers and assigns results to a provided output array.
+
+```javascript
+var Uint32Array = require( '@stdlib/array/uint32' );
+
+var out = new Uint32Array( 2 );
+var v = xor.assign( 1, 2, 3, 4, out, 1, 0 );
+// returns <Uint32Array>[ 2, 6 ]
+
+var bool = ( out === v );
+// returns true
+```
+
+The function supports the following parameters:
+
+-   **ah**: high 32-bit word of the first 64-bit unsigned integer.
+-   **al**: low 32-bit word of the first 64-bit unsigned integer.
+-   **bh**: high 32-bit word of the second 64-bit unsigned integer.
+-   **bl**: low 32-bit word of the second 64-bit unsigned integer.
+-   **out**: output array.
+-   **stride**: stride length for `out`.
+-   **offset**: starting index for `out`.
+
+#### xor.strided( a, sa, oa, b, sb, ob, out, so, oo )
+
+Computes the bitwise XOR of two 64-bit unsigned integers stored in integer-valued strided array views and assigns results to a provided strided output array.
+
+```javascript
+var Uint32Array = require( '@stdlib/array/uint32' );
+
+var a = new Uint32Array( [ 1, 2 ] );
+var b = new Uint32Array( [ 3, 4 ] );
+var out = new Uint32Array( 2 );
+
+var v = xor.strided( a, 1, 0, b, 1, 0, out, 1, 0 );
+// returns <Uint32Array>[ 2, 6 ]
+
+var bool = ( out === v );
+// returns true
+```
+
+The function supports the following parameters:
+
+-   **a**: first 64-bit unsigned integer strided array view containing interleaved 32-bit unsigned integer high and low order words.
+-   **sa**: stride length for `a`.
+-   **oa**: starting index for `a`.
+-   **b**: second 64-bit unsigned integer strided array view containing interleaved 32-bit unsigned integer high and low order words.
+-   **sb**: stride length for `b`.
+-   **ob**: starting index for `b`.
+-   **out**: output array.
+-   **so**: stride length for `out`.
+-   **oo**: starting index for `out`.
