function croundf( z ) {
	return new Complex64( roundf( real( z ) ), roundf( imag( z ) ) );
}
Rounds each component of a single-precision complex floating-point number to the nearest integer.

@param {Complex64} z - complex number
@returns {Complex64} rounded complex number

@example
var Complex64 = require( '@stdlib/complex/float32/ctor' );
var real = require( '@stdlib/complex/float32/real' );
var imag = require( '@stdlib/complex/float32/imag' );

var v = croundf( new Complex64( -4.2, 5.5 ) );
// returns <Complex64>

var re = real( v );
// returns -4.0

var im = imag( v );
// returns 6.0

v = croundf( new Complex64( 9.99999, 0.1 ) );
// returns <Complex64>

re = real( v );
// returns 10.0

im = imag( v );
// returns 0.0

v = croundf( new Complex64( 0.0, 0.0 ) );
// returns <Complex64>

re = real( v );
// returns 0.0

im = imag( v );
// returns 0.0

v = croundf( new Complex64( NaN, NaN ) );
// returns <Complex64>

re = real( v );
// returns NaN

im = imag( v );
// returns NaN
