function dsnansumpw( N, x, strideX, offsetX ) {
	return addon.ndarray( N, x, strideX, offsetX );
}
Computes the sum of single-precision floating-point strided array elements, ignoring `NaN` values, using pairwise summation with extended accumulation, and returning an extended precision result.

@param {PositiveInteger} N - number of indexed elements
@param {Float32Array} x - input array
@param {integer} strideX - stride length
@param {NonNegativeInteger} offsetX - starting index
@returns {number} sum

@example
var Float32Array = require( '@stdlib/array/float32' );
var floor = require( '@stdlib/math/base/special/floor' );

var x = new Float32Array( [ 2.0, 1.0, 2.0, -2.0, -2.0, 2.0, 3.0, 4.0, NaN, NaN ] );

var v = dsnansumpw( 5, x, 2, 1 );
// returns 5.0
