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

@param {number} x - single-precision floating-point number
@returns {Array<number>} output array

@example
var toFloat32 = require( '@stdlib/number/float64/base/to-float32' );

var v = normalizef( toFloat32( 1.401e-45 ) );
// returns [ 1.1754943508222875e-38, -23 ]

@example
var v = normalizef( 0.0 );
// returns [ 0.0, 0 ]

@example
var PINF = require( '@stdlib/constants/float32/pinf' );

var v = normalizef( PINF );
// returns [ +Infinity, 0 ]

@example
var NINF = require( '@stdlib/constants/float32/ninf' );

var v = normalizef( NINF );
// returns [ -Infinity, 0 ]

@example
var v = normalizef( NaN );
// returns [ NaN, 0 ]
