/**
* Compute the sum of absolute values (L1 norm) of double-precision floating-point strided array elements, ignoring `NaN` values and using ordinary recursive summation.

* @module @stdlib/blas/ext/base/dnanasumors
*
* @example
* var Float64Array = require( '@stdlib/array/float64' );
* var dnanasumors = require( '@stdlib/blas/ext/base/dnanasumors' );
*
* var x = new Float64Array( [ 1.0, -2.0, NaN, 2.0 ] );
*
* var v = dnanasumors( x.length, x, 1 );
* // returns 5.0
*
* @example
* var Float64Array = require( '@stdlib/array/float64' );
* var dnanasumors = require( '@stdlib/blas/ext/base/dnanasumors' );

* var x = new Float64Array( [ 2.0, 1.0, 2.0, -2.0, -2.0, 2.0, 3.0, 4.0, NaN, NaN ] );
