Hi,
i have working hours of employee. Like
hours1=8.0
hours2=10.5

Now to get sum of hours,i first multiply hours hand with 60 and then sum it with minutes hand.
sum = (sum + (hh * 60) + mm);

Now to get total hours divided sum by 60
sum = Math.Round(sum / 60, 2);

and the result is
sum=18.83

Now i want to display 18.83 like 18.5

Please give me any solution if any will have.

Thanks.

How about using the DateTime class instead?

It has all the methods that you want...

Solution 1

You should use TimeSpans.
This way:

C#

TimeSpan ts1 = TimeSpan.FromHours(8);
TimeSpan ts2 = TimeSpan.FromHours(10.5);
TimeSpan total = ts1 + ts2;
MessageBox.Show(total.TotalHours.ToString());

hours1 and hours2 is just an example, may be more than five hours be there and i am summing up all that hours. i just want to convert 18.83 into 18.50

The number of hours you have to sum is irrelevant ; TimeSpan is the only one reasonable solution to compute time-related values.
Moreover, if the actual algorithm you use returns 18.83 from the values 10.5 and 8, there is a problem in your algorithm ; trying to convert a false value into a right one is just silly, better implement an algorithm that will give you the right answer in the first place (thus, TimeSpans).
