+#### isSameFloat64Array( v1, v2 )
+
+Tests if two arguments are both [Float64Arrays][@stdlib/array/float64] and have the [same values][@stdlib/assert/is-same-value].
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+
+var x = new Float64Array( [ 1.0, 2.0 ] );
+var y = new Float64Array( [ 1.0, 2.0 ] );

+
+## Notes
+
+-   In contrast to the strict equality operator `===`, the function distinguishes between `+0` and `-0` and treats `NaNs` as the [same value][@stdlib/assert/is-same-value].

+{{alias}}( v1, v2 )
+    Tests if two arguments are both Float64Arrays and have the same values.
+
+    The function differs from the `===` operator in that the function treats
+    `-0` and `+0` as distinct and `NaNs` as the same.
+
+    Parameters
+    ----------
+    v1: any
+        First input value.
+
+    v2: any
+        Second input value.
+
+    Returns
+    -------
+    bool: boolean
+        Boolean indicating whether two arguments are the same.
+
+    Examples
+    --------
+    > var x = new {{alias:@stdlib/array/float64}}( [ 1.0, 2.0, 3.0 ] );
