How do I change the data type？like a: "644488000.0000" ---->a:644488000.0000

Hi! I use evolutility-server-node and evolutility-ui-jquery. The project is set up, but there are problems when filtering is used. I need to filter the data based on the size of the number, but the browser gets the data in the form of a string, not a number. I tried to solve it, but failed.


               #  evolutility-server-node/models/organizer/test.js
                {
            "id": "a",
            "type": "decimal",
            "inMany": true,
            "column": "a"
        }
              # evolutility-ui-jquery/models/test.js
               {
                    id: 'a', 
                   attribute: 'a', 
                   type: 'decimal',
                   label:'a', 
                   inMany: true,                 
                }
