+# sladiv
+
+> Divide two single-precision complex floating-point numbers in real arithmetic.
+
+<section class="usage">
+
+## Usage
+
+```javascript
+var sladiv = require( '@stdlib/lapack/base/sladiv' );
+```
+
+#### sladiv( a, b, c, d, P, Q )
+
+Divides two single-precision complex floating-point numbers in real arithmetic.
+
+```javascript
+var Float32Array = require( '@stdlib/array/float32' );
+
+var P = new Float32Array( 1 );
+var Q = new Float32Array( 1 );
+
+sladiv( -13.0, -1.0, -2.0, 1.0, P, Q );
+// P => <Float32Array>[ 5.0 ]
+// Q => <Float32Array>[ 3.0 ]
+```
+
+The function has the following parameters:
+
+-   **a**: real component of numerator.
+-   **b**: imaginary component of numerator.
+-   **c**: real component of denominator.
+-   **d**: imaginary component of denominator.
+-   **P**: [`Float32Array`][mdn-float32array] containing a single element which is overwritten by the real part of the quotient.
+-   **Q**: [`Float32Array`][mdn-float32array] containing a single element which is overwritten by the imaginary part of the quotient.
+
+#### sladiv.ndarray( a, b, c, d, P, offsetP, Q, offsetQ )
+
+Divides two single-precision complex floating-point numbers in real arithmetic using alternative indexing semantics.
+
+```javascript
+var Float32Array = require( '@stdlib/array/float32' );
+
+var P = new Float32Array( 1 );
+var Q = new Float32Array( 1 );
+
+sladiv.ndarray( -13.0, -1.0, -2.0, 1.0, P, 0, Q, 0 );
+// P => <Float32Array>[ 5.0 ]
+// Q => <Float32Array>[ 3.0 ]
+```
+
+The function has the following parameters:
+
+-   **a**: real component of numerator.
+-   **b**: imaginary component of numerator.
+-   **c**: real component of denominator.
+-   **d**: imaginary component of denominator.
+-   **P**: [`Float32Array`][mdn-float32array] containing an element which is overwritten by the real part of the quotient.
+-   **offsetP**: index of the element in `P`.
+-   **Q**: [`Float32Array`][mdn-float32array] containing an element which is overwritten by the imaginary part of the quotient.
+-   **offsetQ**: index of the element in `Q`.
+
+While [`typed array`][mdn-typed-array] views mandate a view offset based on the underlying buffer, the offset parameters support indexing semantics based on starting indices. For example,
+
+```javascript
+var Float32Array = require( '@stdlib/array/float32' );
+
+var P = new Float32Array( [ 0.0, 0.0, 0.0 ] );
+var Q = new Float32Array( [ 0.0, 0.0, 0.0 ] );
+
+sladiv.ndarray( 2.0, 1.0, 3.0, 4.0, P, 1, Q, 2 );
+// P => <Float32Array>[ 0.0, 0.4, 0.0 ]
+// Q => <Float32Array>[ 0.0, 0.0, -0.2 ]
+```
