+#### cceil.assign( re, im, out, strideOut, offsetOut )
+
+Rounds each component of a double-precision complex floating-point number toward positive infinity and assigns results to a provided output array.
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+
+var out = new Float64Array( 2 );
+var v = cceil.assign( -1.5, 2.5, out, 1, 0 );
+// returns <Float64Array>[ -1.0, 3.0 ]
+
+var bool = ( out === v );
+// returns true
+```
+
+The function supports the following parameters:
+
+-   **re**: real component.
+-   **im**: imaginary component.
+-   **out**: output array.
+-   **strideOut**: stride length for `out`.
+-   **offsetOut**: starting index for `out`.
+
+#### cceil.strided( z, sz, oz, out, so, oo )
+
+Rounds each component of a double-precision complex floating-point number stored in a real-valued strided array view toward positive infinity and assigns results to a provided strided output array.
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+
+var z = new Float64Array( [ -1.5, 2.5 ] );
+var out = new Float64Array( 2 );
+
+var v = cceil.strided( z, 1, 0, out, 1, 0 );
+// returns <Float64Array>[ -1.0, 3.0 ]
+
+var bool = ( out === v );
+// returns true
+```
+
+The function supports the following parameters:
+
+-   **z**: complex number strided array view.
+-   **sz**: stride length for `z`.
+-   **oz**: starting index for `z`.

+-   **so**: stride length for `out`.
