Suggested change

if ( N <= 0 ) {

return NaN;

}

this is already being checked for in ndarray.js

kindly refer to this to see how we write examples. also, use generic data type instead of float64

 ```javascript
-var floor = require( '@stdlib/math/base/special/floor' );
-
 var x = [ 2.0, 1.0, 2.0, -2.0, -2.0, 2.0, 3.0, 4.0 ];


Suggested change

var x = [ 2.0, 1.0, 2.0, -2.0, -2.0, 2.0, 3.0, 4.0 ];

var x = [ 2.0, 1.0, 2.0, -2.0, -2.0, 2.0, 3.0, 4.0, NaN, NaN ];

we should explicitly show how we're handling the NaN element
