I don't think you ever need to truncate or round any number. There are functions to that, but they are needed in rare esoteric cases.

What you probably need is to present a number in the form of string the way it would look rounded. You really need to do that only when you want to show something on screen.

So, you just need to use formatting via string.Format or double.ToString(string format). For format strings, see:

Solution 1

Try as below code.

C#

double d = 133.2;

Int32 num1 = Convert.ToInt32(Math.Truncate(d));

//Or as below

Int64 num2 = Convert.ToInt64(Math.Truncate(d));

Voted 3, You try this code for "133.8" and see the result.

Nitesh Kejriwal 20-Nov-11 11:36am

It would return 134

RaisKazi 20-Nov-11 12:39pm

Exactly, I think OP wants value before decimal place(In this case it should return 133). Changing my Vote to 4, as OP's requirement is not very clear. Please have a look at my Answer too.

Rais, I agree with your solution too. The question is not very clear..I voted 4 too..

Solution 3

Try
Math.Round Method (Double)[^]
Rounds a double-precision floating-point value to the nearest integral value.

C#

double d = 133.2;
d = Math.Round(d); // d will hold 133
