+#### TypedArrayFE.prototype.findIndex( callbackFn\[, thisArg] )
+
+Tests whether all the elements in an array pass a test implemented by a predicate function.
+
+```javascript
+function greaterthantwo( v ) {
+    return ( v > 2.0 );
+}
+
+var Float64ArrayFE = fixedEndianFactory( 'float64' );
+
+var arr = new Float64ArrayFE( 'little-endian', 3 );
+
+arr.set( 1.5, 0 );
+arr.set( 2.5, 1 );
+arr.set( 3.5, 2 );
+
+var bool = arr.every( isNegative );
+// returns true
+```
+
+The invoked function is provided three arguments:
+
+-   **value**: current array element.
+-   **index**: current array element index.
+-   **arr**: the array on which this method was called.
+
+To set the function execution context, provide a `thisArg`.
+
+```javascript
+function isPositive( v, i ) {
+    this.count += 1;
+    return v > 0;
+}
+
+var Float64ArrayFE = fixedEndianFactory( 'float64' );
+
+var arr = new Float64ArrayFE( 'little-endian', [ 1.0, 2.0, -3.0 ] );
+
+var context = {
+    'count': 0
+};
+
+var bool = arr.every( isPositive, context );
+// returns false
+
+var count = context.count;
+// returns 3
+```
