Why is NumericTextBox saving the values as String in Mongodb?

[Youssef Lakdime]

I have added a NumericTextBox to event editor so users can enter a Distance (in kilometers). My code is like this:

let row: HTMLElement = createElement('div', {className: 'custom-field-row'});

let container: HTMLElement = createElement('div', {className: 'custom-field-container'});

let inputEle2: HTMLInputElement = createElement('input', {
  className: 'e-field', attrs: {name: 'km'}
}) as HTMLInputElement;

row.appendChild(container);

let distanceTextBox:  NumericTextBox = new  NumericTextBox({

  value: 88,
  format: 'n0',
  floatLabelType: 'Auto',
  placeholder: 'Kilometers'
  //enableRtl: true
});

distanceTextBox.appendTo(inputEle2);
inputEle2.setAttribute('name', 'km');


I have tried playing around with different settings, like format: 'n0' but the value gets saved as a string nevertheless and i cannot do any calculations with them.
Any help would be appreciated.

ScheduleData in the MongoDB:

{
    "_id": {
        "$oid": "5e8a43220e1de11fe051e670"
    },
    "km": "92", <- this value is in quotation marks, i need it to be a number
    "isFormal": false,
    "Subject": "ewfwefewf",
    "Location": "ewfwefewf",
    "StartTime": {
        "$date": "2020-04-11T16:30:00.000Z"
    },
    "EndTime": {
        "$date": "2020-04-11T17:00:00.000Z"
    },
    "IsAllDay": false,
    "StartTimezone": null,
    "EndTimezone": null,
    "Description": "wefwef",
    "RecurrenceRule": null,
    "Id": 7,
    "CreatedBy": "Bob"
}
