#### Complex128Array.prototype.every( predicate\[, thisArg] )

Returns a boolean indicating whether all elements pass a test.

```javascript
var real = require( '@stdlib/complex/real' );
var imag = require( '@stdlib/complex/imag' );

function predicate( v ) {
return ( real( v ) === imag( v ) );
}

var arr = new Complex128Array( 3 );

// Set the first three elements:
arr.set( [ 1.0, 1.0 ], 0 );
arr.set( [ 2.0, 2.0 ], 1 );
arr.set( [ 3.0, 3.0 ], 2 );

// Check whether all elements pass a test:
var bool = arr.every( predicate );
// returns true
```

The `predicate` 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 predicate( v, i ) {
this.count += 1;
return ( i >= 0 );
}

var arr = new Complex128Array( 3 );

var context = {
'count': 0
};

// Set the first three elements:
arr.set( [ 1.0, 1.0 ], 0 );
arr.set( [ 2.0, 2.0 ], 1 );
arr.set( [ 3.0, 3.0 ], 2 );

var bool = arr.every( predicate, context );
// returns true

var count = context.count;
// returns 3
```
