Hello everyone,

I need your help in finding a Maths Operator. This is what I am looking for:

int A = 5;<br />
int B = 3;<br />
<br />
Double C = A % B; // This will give me the reminder 2<br />
Double D = ?????? // Is there any operator that I can use to get the quotient 1<br />

I know that I can use the reminder and calculate the quotient. But I was wondering if there is an operator which I can use to avoid the mathematically calculating the quotient.

Thank you very much and have a great day.

Because both A and B are integers a simple division would give it to you but generally you can use Casting to do that

double q=(int)(A/B);

good luck

Hi,

if A and B are both integer types (i.e. not float, not double), then A/B will
yield the integer quotient; you can store that in an integer variable, but also
in a float/double, without cast. Hence double q=A/B;

But as soon as one of the operands is a real number, the real quotient will be
calculated.

Looking at his only other posts either this guy is utterly oblivious to us making fun of him or it is a troll. I'm guessing it's the latter.

I just reviewed your other posts just like leckey said

People are here just for helping each other, if you were more polite you could have the answer

here is the article Michael Sync pointed to it and you didn't mention it http://www.codeproject.com/dotnet/twaindotnet.asp

there is another way too, using the Windows Image Acquisition (WIA)

you can search it from Microsoft or just download it from http://hjk.4shared.com

I have googled for 2 days straight with no success...

Scenario: Load simple xml data into listview control with 2 or more columns.

I have used XmlTextReader and XmlReader with very limited success. I am able to populate the listview but only the first column.

If someone could point me in the right direction, I would greatly appreciate it.

I would suggest investigating how to create a DataTable and populate it with your xml. This will not be an easy task but it's by no means overly difficult either. It will just take a bit of work to accomplish. You will have to create each column in the DataTable and fill it with the appropriate data. Once that's done you can bind the DataTable to the ListView and you should be good to go. There may be a way to cut out the DataTable entirely but you may figure that out by researching what I suggested.

Go figure: I post my question and then I find my answer.

Answer lies with XmlDocument. See code snippet below.

My xml file (checklist.xml) is really an index used for parsing files of their data based on a starting point, string size, and a description. In turn these are my columns in my listview control as well.

<br />
private void tsbtnRunAudit_Click( object sender, EventArgs e )<br />
        {<br />
            XmlDocument xdoc = new XmlDocument();<br />
            xdoc.Load(@"C:\DEVELOPMENT\Sandbox\VikConvAudit\VikConvAudit\Indexes\checklist.xml");<br />
<br />
            <br />
            XmlNodeList start = xdoc.GetElementsByTagName("Start");<br />
            XmlNodeList size = xdoc.GetElementsByTagName("Size");<br />
            XmlNodeList description = xdoc.GetElementsByTagName("Description");<br />
<br />
            for(int i = 0; i < start.Count; i++)<br />
            {<br />
                lvMain.Items.Add(start[i].InnerText);<br />
                lvMain.Items[i].SubItems.Add(size[i].InnerText);<br />
                lvMain.Items[i].SubItems.Add(description[i].InnerText);<br />
            }<br />
            <br />
        }<br />
<br />

i want the mod
e.g.

2.6
mod = 6

4.0
mod =0

how can get this in C#

=================
i want function to make this

2.6 =3
2.3 =3
2.1 =3
2.0 =2

is this function allready exist in C#

The modulo operator in C# is %.

However, the modulo operator doesn't do at all what you are asking for. Actually I'm not at all sure what you are actually asking for, but it's not modulo.

That looks like the fraction part of a floating point number. You can do that by using the Math.IEEEReminder method:

double num = 2.6;<br />
double fraction = Math.IEEEReminder(num, 1); // result is 0.6

You have to explain what you mean by that, because it doesn't make any sense at all.

Hi,

I suggest you look into the Math class; it has what you need and more.

The first can be done with 10.0*(floatValue % 1.0) or 10*IEEEremainder,
but you should not call this mod, it is more like 10 times mod

The second is a simple ceiling.

Oh... Is that supposed to be some kind of separator, indicating that the text above it is a separate question from the text below it? I replied assuming that you were talking about the same question.

That was far from obvious... Why not just write "and I have another qustion"?
