Returns a normal number `y` and exponent `exp` satisfying \\(x = y \cdot 2^\mathrm{exp}\\) and assigns results to a provided output array.

@param {number} x - input value
@param {Collection} out - output array
@param {integer} stride - output array stride
@param {NonNegativeInteger} offset - output array index offset
@returns {Collection} output array

@example
var pow = require( '@stdlib/math/base/special/pow' );

var out = normalize( 3.14e-319, [ 0.0, 0 ], 1, 0 );
// returns [ 1.4141234400356668e-303, -52 ]

var y = out[ 0 ];
var exp = out[ 1 ];

var bool = ( y*pow(2.0,exp) === 3.14e-319 );
// returns true

@example
var out = normalize( 0.0, [ 0.0, 0 ], 1, 0 );
// returns [ 0.0, 0 ];

@example
var PINF = require( '@stdlib/constants/float64/pinf' );

var out = normalize( PINF, [ 0.0, 0 ], 1, 0 );
// returns [ Infinity, 0 ]

@example
var NINF = require( '@stdlib/constants/float64/ninf' );

var out = normalize( NINF, [ 0.0, 0 ], 1, 0 );
// returns [ -Infinity, 0 ]

@example
var out = normalize( NaN, [ 0.0, 0 ], 1, 0 );
// returns [ NaN, 0 ]
