I'm working to show double data well in my routes.

From backend I insert the correct numbers but in the route it shows me my number but with other numbers.

I'm looking for the october documentation but every attempt has failed. Images:

My code in routes.php is:

    Route::get('api/{lang}/to_add', function( $lang ) {
    $to_adds = To_adds::with( 'image' )->get();

    $add_taxs = new Collection();

    foreach ($to_adds as $key => $value) {
        $to_adds[$key] = $value->lang($lang);

    }
    return $to_adds;
    });

Someone who can help me?
