function normalize( x ) {
	return fcn( x, [ 0.0, 0 ], 1, 0 );
}
Returns a normal number `y` and exponent `exp` satisfying \\(x = y \cdot 2^\mathrm{exp}\\).

@param {number} x - input value
@returns {NumberArray} output array

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

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

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

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

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

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

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