Need to add Condition for Qty Check by Type. Decimal or not

[maghamed]

We have next code

        /**
         * Check quantity type
         */
        $result->setItemIsQtyDecimal($stockItem->getIsQtyDecimal());
        if (!$stockItem->getIsQtyDecimal()) {
            $result->setHasQtyOptionUpdate(true);
            $qty = intval($qty);
            /**
             * Adding stock data to quote item
             */
            $result->setItemQty($qty);
            $qty = $this->getNumber($qty);
            $origQty = intval($origQty);
            $result->setOrigQty($origQty);
        }

In legacy implementation
\Magento\CatalogInventory\Model\StockStateProvider::checkQuoteItemQty

This case is not covered in MSI
