function cidentityf( z ) {
	var v = addon( z );
	return new Complex64( v.re, v.im );
}
Evaluates the identity function for a single-precision complex floating-point number.

@private
@param {Complex64} z - input value
@returns {Complex64} input value

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

var v = cidentityf( new Complex64( -1.0, 2.0 ) );
// returns <Complex64>[ -1.0, 2.0 ]
