+# isUint64
+
+> Test if a value is an [unsigned 64-bit integer][@stdlib/number/uint64/ctor].
+
+
+
+## Usage
+
+```javascript
+var isUint64 = require( '@stdlib/assert/is-uint64' );
+```
+
+#### isUint64( value )
+
+Tests if a value is an [unsigned 64-bit integer][@stdlib/number/uint64/ctor].
+
+```javascript
+var Uint64 = require( '@stdlib/number/uint64/ctor' );
+
+var x = new Uint64( 1234 );
+
+var bool = isUint64( x );
+// returns true
+```
+
+
+
+
+
+
+
+## Examples
+
+
+
+```javascript
+var Uint64 = require( '@stdlib/number/uint64/ctor' );
+var Complex128 = require( '@stdlib/complex/float64/ctor' );
+var isUint64 = require( '@stdlib/assert/is-uint64' );
+
+console.log( isUint64( new Uint64( 1234 ) ) );
+// => true
+
+console.log( isUint64( new Complex128( 3.0, 1.0 ) ) );
+// => false
+
+console.log( isUint64( {} ) );
+// => false
+
+console.log( isUint64( null ) );
+// => false
