For example, to compute the sum of every other element:\n\n```javascript\nvar Float32Array = require( '@stdlib/array-float32' );\nvar Float64Array = require( '@stdlib/array-float64' );\n\nvar x = new Float32Array( [ 1.0, 2.0, NaN, -7.0, NaN, 3.0, 4.0, 2.0 ] );\nvar out = new Float64Array( 2 );\n\nvar v = dsnannsumors( 4, x, 2, out, 1 );\n// returns \u003cFloat64Array\u003e[ 5.0, 2 ]\n```\n\nNote that indexing is relative to the first index. To introduce an offset, use [`typed array`][mdn-typed-array] views.\n\n\u003c!-- eslint-disable stdlib/capitalized-comments --\u003e\n\n```javascript\nvar Float32Array = require( '@stdlib/array-float32' );\nvar Float64Array = require( '@stdlib/array-float64' );\n\nvar x0 = new Float32Array( [ 2.0, 1.0, NaN, -2.0, -2.0, 2.0, 3.0, 4.0 ] );\nvar x1 = new Float32Array( x0.buffer, x0.BYTES_PER_ELEMENT*1 ); // start at 2nd element\n\nvar out0 = new Float64Array( 4 );\nvar out1 = new Float64Array( out0.buffer, out0.BYTES_PER_ELEMENT*2 ); // start at 3rd element\n\nvar v = dsnannsumors( 4, x1, 2, out1, 1 );\n// returns \u003cFloat64Array\u003e[ 5.0, 4 ]\n```\n\n#### dsnannsumors.ndarray( N, x, strideX, offsetX, out, strideOut, offsetOut )\n\nComputes the sum of single-precision floating-point strided array elements, ignoring `NaN` values, using ordinary recursive summation with extended accumulation and alternative indexing semantics, and returning an extended precision result.\n\n```javascript\nvar Float32Array = require( '@stdlib/array-float32' );\nvar Float64Array = require( '@stdlib/array-float64' );\n\nvar x = new Float32Array( [ 1.0, -2.0, NaN, 2.0 ] );\nvar out = new Float64Array( 2 );\n\nvar v = dsnannsumors.ndarray( x.length, x, 1, 0, out, 1, 0 );\n// returns \u003cFloat64Array\u003e[ 1.0, 3 ]\n```\n\nThe function has the following additional parameters:\n\n-   **offsetX**: starting index for `x`.\n-   **offsetOut**: starting index for `out`.\n\nWhile [`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 sum of every other element starting from the second element:\n\n```javascript\nvar Float32Array = require( '@stdlib/array-float32' );\nvar Float64Array = require( '@stdlib/array-float64' );\n\nvar x = new Float32Array( [ 2.0, 1.0, NaN, -2.0, -2.0, 2.0, 3.0, 4.0 ] );\nvar out = new Float64Array( 4 );\n\nvar v = dsnannsumors.ndarray( 4, x, 2, 1, out, 2, 1 );\n// returns \u003cFloat64Array\u003e[ 0.0, 5.0, 0.0, 4 ]\n```\n\n\u003c/section\u003e\n\n\u003c!-- /.usage --\u003e\n\n\u003csection class=\"notes\"\u003e\n\n## Notes\n\n-   If `N \u003c= 0`, both functions return a sum equal to `0.0`.\n-   Accumulated intermediate values are stored as double-precision floating-point numbers.\n\n\u003c/section\u003e\n\n\u003c!-- /.notes --\u003e\n\n\u003csection class=\"examples\"\u003e\n\n## Examples\n\n\u003c!-- eslint no-undef: \"error\" --\u003e\n\n```javascript\nvar discreteUniform = require( '@stdlib/random-base-discrete-uniform' );\nvar bernoulli = require( '@stdlib/random-base-bernoulli' );\nvar filledarrayBy = require( '@stdlib/array-filled-by' );\nvar Float32Array = require( '@stdlib/array-float32' );\nvar Float64Array = require( '@stdlib/array-float64' );\nvar dsnannsumors = require( '@stdlib/blas-ext-base-dsnannsumors' );\n\nfunction rand() {\n    if ( bernoulli( 0.5 ) \u003c 0.2 ) {\n        return NaN;\n    }\n    return discreteUniform( 0, 100 );\n}\n\nvar x = filledarrayBy( 10, 'float32', rand );\nconsole.log( x );\n\nvar out = new Float64Array( 2 );\ndsnannsumors( x.length, x, 1, out, 1 );\nconsole.log( out );\n```\n\n\u003c/section\u003e\n\n\u003c!-- /.examples --\u003e\n\n\u003c!-- C interface documentation. --\u003e\n\n* * *\n\n\u003csection class=\"c\"\u003e\n\n## C APIs\n\n\u003c!-- Section to include introductory text.
