如何进行比较cakephp 3.x上的浮点值的查询？

Question

我是Cakephp的新手，我试图在搜索区域中列出一些价格大于或小于值的产品并进行分页。

但是当我尝试这样做时，结果与我所期望的完全不同。当试图了解为什么会发生这种情况时，我发现我的查询将值当作String类型而不是Float处理，并且弄乱了结果。

无论我尝试什么，值的类型都不会改变，如何在cakePHP查询中更改值的类型？

// the price value that comes from the input is formatted like this: '1.000,00'

$productsModel = $this->loadModel('Products');

$this->paginate = [
    'contain' => [
       'Archives', 'Categories', 'Favorites'
    ],
    'conditions' => [
        //here I've tried to do some conversions manually
        'Products.price >=' => floatVal(str_replace(",", ".", str_replace(".", "", $data['lower_price']))),
        'Products.price <=' => floatVal(str_replace(",", ".", str_replace(".", "", $data['greater_price']))
    ],
    'limit' => 16
];
$products = $this->paginate($productsModel);

$this->set(compact('products'));

我期望查询是这样生成的：

SELECT * FROM products WHERE price >= 29.90;

但是我有这个：

SELECT * FROM products WHERE price >= '29.90';
