+## Usage
+
+```javascript
+var sindexOf = require( '@stdlib/blas/ext/base/sindex-of' );
+```
+
+#### sindexOf( N, searchElement, x, strideX )
+
+Returns the index of a specified search element in a single-precision floating-point strided array.
+
+```javascript
+var Float32Array = require( '@stdlib/array/float32' );
+
+var x = new Float32Array( [ -2.0, 1.0, 3.0, -5.0, 4.0, 0.0, -1.0, 3.0 ] );
+
+var idx = sindexOf( x.length, 3.0, x, 1 );
+// returns 2
+```
+
+The function has the following parameters:
+
+-   **N**: number of indexed elements.
+-   **searchElement**: search element.
+-   **x**: input [`Float32Array`][@stdlib/array/float32].
+-   **strideX**: stride length.
+
+If the function is unable to find a search element, the function returns `-1`.
+
+```javascript
+var Float32Array = require( '@stdlib/array/float32' );
+
+var x = new Float32Array( [ -2.0, 1.0, 3.0, -5.0, 4.0, 0.0, -1.0, 3.0 ] );
+
+var idx = sindexOf( x.length, 8.0, x, 1 );
+// returns -1
+```
+
+The `N` and stride parameters determine which elements in the strided array are accessed at runtime. For example, to search every other element:
+
+```javascript
+var Float32Array = require( '@stdlib/array/float32' );
+
+var x = new Float32Array( [ -2.0, 1.0, 3.0, -5.0, 4.0, 0.0, -1.0, 3.0 ] );
+
+var idx = sindexOf( 4, -1.0, x, 2 );
+// returns 3
+```
+
+Note that indexing is relative to the first index. To introduce an offset, use [`typed array`][mdn-typed-array] views.
+
+```javascript
+var Float32Array = require( '@stdlib/array/float32' );
+
+// Initial array...
+var x0 = new Float32Array( [ 1.0, -2.0, 3.0, -4.0, 5.0, -6.0 ] );
+
+// Create an offset view...
+var x1 = new Float32Array( x0.buffer, x0.BYTES_PER_ELEMENT*1 ); // start at 2nd element
+
+// Find index...
+var idx = sindexOf( 3, -6.0, x1, 2 );
+// returns 2
+```
+
+#### sindexOf.ndarray( N, searchElement, x, strideX, offsetX )
+
+Returns the index of a specified search element in a single-precision floating-point strided array using alternative indexing semantics.
+
+```javascript
+var Float32Array = require( '@stdlib/array/float32' );
+
+var x = new Float32Array( [ -2.0, 1.0, 3.0, -5.0, 4.0, 0.0, -1.0, 3.0 ] );
+
+var idx = sindexOf.ndarray( x.length, 3.0, x, 1, 0 );
+// returns 2
+```
+
+The function has the following additional parameters:
+
+-   **offsetX**: starting index.
+
+While [`typed array`][mdn-typed-array] views mandate a view offset based on the underlying buffer, the offset parameter supports indexing semantics based on a starting index. For example, to access only the last three elements of the strided array
+
+```javascript
+var Float32Array = require( '@stdlib/array/float32' );
+
+var x = new Float32Array( [ -2.0, 1.0, 3.0, -5.0, 4.0, 0.0, -1.0, 3.0 ] );
+
+var idx = sindexOf.ndarray( 3, 3.0, x, 1, x.length-3 );
+// returns 2
+```

+
+## Notes
+
+-   When searching for a search element, the function checks for equality using the strict equality operator `===`. As a consequence, `NaN` values are considered distinct, and `-0` and `+0` are considered the same.

+
+{{alias}}( N, searchElement, x, strideX )
+    Returns the index of a specified search element in a single-precision
+    floating-point strided array.
+
+    The `N` and stride parameters determine which elements in the strided array
+    are accessed at runtime.
+
+    Indexing is relative to the first index. To introduce an offset, use a typed
+    array view.
+
+    if `N <= 0`, the function returns `-1`.
+
+    Parameters
+    ----------
+    N: integer
+        Number of indexed elements.
+
+    searchElement: number
+        Search element.
+
+    x: Float32Array
+        Input array.
+
+    strideX: integer
+        Stride length.
+
+    Returns
+    -------
+    out: integer
+        Index or -1.
+
+    Examples
+    --------
+    > var x = new {{alias:@stdlib/array/float32}}( [ -2.0, 1.0, 3.0, -5.0, 4.0, -1.0, -3.0 ] );
+    > var out = {{alias}}( x.length, 1.0, x, 1 )
+    1
+
+
+{{alias}}( N, searchElement, x, strideX, offsetX )
+    Returns the index of a specified search element in a single-precision
+    floating-point strided array using alternative indexing semantics.
+
+    While typed array views mandate a view offset based on the underlying
+    buffer, the offset parameter supports indexing semantics based on a
+    starting index.
+
+    Parameters
+    ----------
+    N: integer
+        Number of indexed elements.
+
+    searchElement: number
+        Search element.
+
+    x: Float32Array
+        Input array.
+
+    strideX: integer
+        Stride length.
+
+    offsetX: integer
+        Starting index.
+
+    Returns
+    -------
+    out: integer
+        Index or -1.
+
+    Examples
+    --------
+    > var x = new {{alias:@stdlib/array/float32}}( [ -2.0, 1.0, 3.0, -5.0, 4.0, -1.0, -3.0 ] );
+    > var out = {{alias}}.ndarray( x.length, 1.0, x, 1, 0 )
