Preventing ASP.Net JSON from dropping trailing 0 in decimal properties

Question

I am using the built in ASP.Net return JSON() function to convert a View Model to JSON, in this View Model one of the properties is a decimal . When this property is filled with a value like 4.50 or 4.00 I have noticed that the JSON version of the View Model is dropping the trailing 0(s). How do I stop this behavior so when I read the data in the JavaScript in the View I get all the 0s?

ViewModel:

public class TimeCardEntryVM
{
    public int ID { get; set; }
    public string ProjectCode { get; set; }
    public string ProjectDescription { get; set; }
    public string TaskCode { get; set; }
    public string TaskDescription { get; set; }
    public bool IsDurationTime { get; set; }
    public decimal HoursWorked { get; set; }
    public DateTime StartTime { get; set; }
    public DateTime EndTime { get; set; }
    public string WorkDescription { get; set; }
}

ASP.Net code that returns the JSON:

{
    var timeEntryData = db.TimeCards
                            .Include(timeCard => timeCard.Project)
                            .Include(timeCard => timeCard.Task)
                            .Where(timeCard => timeCard.ID == timeCardID)
                            .Select(timeCard => new TimeCardEntryVM()
                            {
                                ID = timeCard.ID,
                                EndTime = timeCard.EndDateTime,
                                ProjectCode = timeCard.Project.Code,
                                ProjectDescription = timeCard.Project.Description,
                                StartTime = timeCard.StartDateTime,
                                TaskCode = timeCard.Task.Code,
                                TaskDescription = timeCard.Task.Description,
                                HoursWorked = (decimal)timeCard.TimeWorked,
                                IsDurationTime = timeCard.IsDurationTime,
                                WorkDescription = timeCard.WorkDescription
                            }).First();

    return Json(timeEntryData, JsonRequestBehavior.AllowGet);
}

JavaScript code I am using to check the value:

$.ajax({
    type: "POST",
    url: "/TimeCard/TimeCardEntry",
    data: { timeCardID: args.row["uid"] },
    success: function (data)
    {
        alert(data["HoursWorked"]);
    }
});

Why not just format the result in JavaScript using .toFixed() :

$.ajax({
    type: "POST",
    url: "/TimeCard/TimeCardEntry",
    data: { timeCardID: args.row["uid"] },
    success: function (data)
    {
        var formattedHours = data.HoursWorked.toFixed(2);
    }
});
