+## Usage
+
+```javascript
+var dnancusumkbn2 = require( '@stdlib/blas/ext/base/dnancusumkbn2' );
+```
+
+#### dnancusumkbn2( N, sum, x, strideX, y, strideY )
+
+Computes the cumulative sum of double-precision floating-point strided array elements,ignoring `NaN` values and using a second-order iterative Kahan–Babuška algorithm.
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+
+var x = new Float64Array( [ 1.0, -2.0, NaN ] );
+var y = new Float64Array( x.length );
+
+dnancusumkbn2( x.length, 0.0, x, 1, y, 1 );
+// y => <Float64Array>[ 1.0, -1.0, -1.0 ]
+
+x = new Float64Array( [ 1.0, -2.0, NaN ] );
+y = new Float64Array( x.length );
+
+dnancusumkbn2( x.length, 10.0, x, 1, y, 1 );
+// y => <Float64Array>[ 11.0, 9.0, 9.0 ]
+```
+
+The function has the following parameters:
+
+-   **N**: number of indexed elements.
+-   **sum**: initial sum.
+-   **x**: input [`Float64Array`][@stdlib/array/float64].
+-   **strideX**: stride length for `x`.
+-   **y**: output [`Float64Array`][@stdlib/array/float64].
+-   **strideY**: stride length for `y`.
+
+The `N` and stride parameters determine which elements in the strided arrays are accessed at runtime. For example, to compute the cumulative sum of every other element:
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+
+var x = new Float64Array( [ 1.0, 2.0, 2.0, -7.0, NaN, 3.0, 4.0, 2.0 ] );
+var y = new Float64Array( x.length );
+
+var v = dnancusumkbn2( 4, 0.0, x, 2, y, 1 );
+// y => <Float64Array>[ 1.0, 3.0, 3.0, 7.0, 0.0, 0.0, 0.0, 0.0 ]
+```
+
+Note that indexing is relative to the first index. To introduce an offset, use [`typed array`][mdn-typed-array] views.
+
+<!-- eslint-disable stdlib/capitalized-comments -->
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+
+// Initial arrays...
+var x0 = new Float64Array( [ 2.0, NaN, 2.0, NaN, -2.0, 2.0, 3.0, 4.0 ] );
+var y0 = new Float64Array( x0.length );
+
+// Create offset views...
+var x1 = new Float64Array( x0.buffer, x0.BYTES_PER_ELEMENT*1 ); // start at 2nd element
+var y1 = new Float64Array( y0.buffer, y0.BYTES_PER_ELEMENT*3 ); // start at 4th element
+
+dnancusumkbn2( 4, 0.0, x1, -2, y1, 1 );
+// y0 => <Float64Array>[ 0.0, 0.0, 0.0, 4.0, 6.0, 6.0, 6.0, 0.0 ]
+```
+
+#### dnancusumkbn2.ndarray( N, sum, x, strideX, offsetX, y, strideY, offsetY )
+
+Computes the cumulative sum of double-precision floating-point strided array elements, ignoring `NaN` values and using a second-order iterative Kahan–Babuška algorithm and alternative indexing semantics.
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+
+var x = new Float64Array( [ 1.0, -2.0, NaN ] );
+var y = new Float64Array( x.length );
+
+dnancusumkbn2.ndarray( x.length, 0.0, x, 1, 0, y, 1, 0 );
+// y => <Float64Array>[ 1.0, -1.0, -1.0 ]
+```
+
+The function has the following additional parameters:
+
+-   **offsetX**: starting index for `x`.
+-   **offsetY**: starting index for `y`.
+
+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, to calculate the cumulative sum of every other value in `x` starting from the second value and to store in the last `N` elements of `y` starting from the last element:
+
+```javascript
+var Float64Array = require( '@stdlib/array/float64' );
+
+var x = new Float64Array( [ 2.0, 1.0, 2.0, NaN, -2.0, 2.0, 3.0, NaN ] );
+var y = new Float64Array( x.length );
+
+dnancusumkbn2.ndarray( 4, 0.0, x, 2, 1, y, -1, y.length-1 );
+// y => <Float64Array>[ 0.0, 0.0, 0.0, 0.0, 3.0, 3.0, 1.0, 1.0 ]
+```

+{{alias}}( N, sum, x, strideX, y, strideY )
+    Computes the cumulative sum of double-precision floating-point strided
+    array elements, ignoring `NaN` values and using a second-order
+    iterative Kahan–Babuška algorithm.
+
+    The `N` and stride parameters determine which elements in the strided arrays
+    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 `y` unchanged.
+
+    Parameters
+    ----------
+    N: integer
+        Number of indexed elements.
+
+    sum: number
+        Initial sum.
+
+    x: Float64Array
+        Input array.
+
+    strideX: integer
+        Stride length for `x`.
+
+    y: Float64Array
+        Output array.
+
+    strideY: integer
+        Stride length for `y`.
+
+    Returns
+    -------
+    out: Float64Array
+        Output array.
+
+    Examples
+    --------
+    // Standard Usage:
+    > var x = new {{alias:@stdlib/array/float64}}( [ 1.0, -2.0, NaN ] );
+    > var y = new {{alias:@stdlib/array/float64}}( x.length );
+    > {{alias}}( x.length, 0.0, x, 1, y, 1 )
+    <Float64Array>[ 1.0, -1.0, -1.0 ]
+
+    // Using `N` and stride parameters:
+    > x = new {{alias:@stdlib/array/float64}}( [ -2.0, 1.0, 1.0, -5.0, NaN, -1.0 ] );
+    > y = new {{alias:@stdlib/array/float64}}( x.length );
+    > {{alias}}( 3, 0.0, x, 2, y, 2 )
+    <Float64Array>[ -2.0, 0.0, -1.0, 0.0, -1.0, 0.0 ]
+
+    // Using view offsets:
+    > var x0 = new {{alias:@stdlib/array/float64}}( [ 1.0, -2.0, 3.0, 2.0, 5.0, NaN ] );
+    > var y0 = new {{alias:@stdlib/array/float64}}( x0.length );
+    > var x1 = new {{alias:@stdlib/array/float64}}( x0.buffer, x0.BYTES_PER_ELEMENT*1 );
+    > var y1 = new {{alias:@stdlib/array/float64}}( y0.buffer, y0.BYTES_PER_ELEMENT*3 );
+    > {{alias}}( 3, 0.0, x1, 2, y1, 1 )

+
+
+{{alias}}.ndarray( N, sum, x, strideX, offsetX, y, strideY, offsetY )
+    Computes the cumulative sum of double-precision floating-point strided
+    array elements, ignoring `NaN` values and using a second-order iterative
+    Kahan–Babuška algorithm and alternative indexing semantics.
+
+    While typed array views mandate a view offset based on the underlying
+    buffer, the offset parameters support indexing semantics based on starting
+    indices.
+
+    Parameters
+    ----------
+    N: integer
