/**
* Fills a single-precision floating-point ndarray with a specified scalar constant.
*
* ## Notes
*
* - The function expects the following ndarrays:
*
* - a one-dimensional input/output ndarray.
* - a zero-dimensional ndarray containing the scalar constant to fill with.
*
* @param {ArrayLikeObject<Object>} arrays - array-like object containing ndarrays
* @returns {ndarray} input/output ndarray
*
* @example
* var Float32Array = require( '@stdlib/array/float32' );
* var ndarray = require( '@stdlib/ndarray/base/ctor' );
* var scalar2ndarray = require( '@stdlib/ndarray/from-scalar' );
*
* var x = ndarray( 'float32', new Float32Array( [ 1.0, 2.0, 3.0, 4.0 ] ), [ 4 ], [ 1 ], 0, 'row-major' );
*
* var alpha = scalar2ndarray( 5.0, {
* 'dtype': 'float32'
* });
*
* var out = sfill( [ x, alpha ] );
* // returns <ndarray>
*
* var data = out.data;
* // returns <Float32Array>[ 5.0, 5.0, 5.0, 5.0 ]
