Well if you cannot find it by searching the internet then you will have to write it yourself.

Hey.
I am trying to get my program to display only 2 decimals of the result og an calculation.
Code:
dansk = System::Convert::ToDouble(textBox2->Text);
kurs = System::Convert::ToDouble(numericUpDown1->Text);
tysk = dansk / kurs;
ti = tysk * 0.90;
femten = tysk * 0.85;
tyve = tysk * 0.82;
bdansk = tysk * kurs * 1.25;
bti = tysk * 0.90 * 1.25;
bfemten = tysk * 0.85 * 1.25;
btyve = tysk * 0.82 * 1.25;
btysk = tysk * 1.18;
label7->Text = System::Convert::ToString(dansk) + " Kr";
label8->Text = System::Convert::ToString(ti) + " Kr";
label9->Text = System::Convert::ToString(femten) + " Kr";
label10->Text = System::Convert::ToString(tyve) + " Kr";
label14->Text = System::Convert::ToString(bdansk) + " Kr";
label15->Text = System::Convert::ToString(bti) + " Kr";
label16->Text = System::Convert::ToString(bfemten) + " Kr";
label17->Text = System::Convert::ToString(btyve) + " Kr";
label20->Text = System::Convert::ToString(tysk) + " Eur";
label21->Text = System::Convert::ToString(btysk) + " Eur";
My ints are defined another place in my prpgram.
Right now my result will be something like 54.867563547, and not 54.86, as my wish is.
Can you help ?

I need a bit more then that... its my second C++ program..
|

There are lots of samples in the two links I gave you, that show how you can get your output formatted correctly. This may only be your second program but you need to get familiar with the documentation as soon as possible.
For the record you would show the Danish kroner sample as:
label7->Text = String.Format("{0:N} Kr", dansk);
However, if you look at the second link it explains how to get a number shown in different currencies automatically, by selecting the appropriate locale.

I am sorry... But I aint getting anything out of what is explained in the links.
I tried to use the: label7->Text = String.Format("{0:N} Kr", dansk); as you said.
I just get a lot of errors:
warning C4832: token '.' is illegal after UDT 'System::String'
error C2275:'System::String' : illegal use of this type as an expression
error C2228: left of '.Format' must have class/struct/union
I guess its when I remove the Convert part of the line the problem comes ?

That does not look like C++/CLI code to me; more like C#. I guess you didn't look too closely at the example code[^].

I am using Microsoft Visual Studio 2010
|
|
|
|
|
And what is the relevance of that? You do realise that Visual Studio is a development environment and not a programming language?

Be cource the errorcodes I got was from MS Visual C++ 2010.
I thought it might explain to you why I got thoose errorcodes in C++.
Its C++ I am Using.

This is the C++/CLI forum; which are you using, C++/CLI or unmanaged C++?

I have no idea.
Thought I could get some help here ?

Seriously? You are writing a program and you do not know what language or framework you are using? I don't know how you expect us to help if you cannot answer such a basic question. I would suggest you make a decision which language you plan to use and get hold of a book to learn the basics of it before trying anything else.

Thanks for the help.
But i gotta say, I feel it a is waste of time to try and get anything usefull out of you.
All I ask for, is that you write one line of code with my own data in C++. But instead i feel you blame me for not knowing anything, even though that was one of the first things i told you.
I will try my luck some other time.

No, you have not asked that, you asked how to get a number formatted in a particular way in C++/CLI, and I referred you to the documentation that explains it in detail, with plenty of samples. It seems you are not prepared to spend the time reading it. You also do not seem to know exactly which language you are using, so I cannot answer the question, because it would be different for each language.

Neither did I blame you for anything. I have done my best to help you but I cannot answer the question unless I get the proper facts to start with. As I said before, you need to decide which version of the language you are using and start studying it. Give us the proper facts and background to your problem and we will try to help, but you are expected to do some of the work for yourself.

1 - convert them to float type , example :
{
double a = 2.1589687489;
String^ b = Convert::ToString((float)a);
}
2 - remove them , example :
{
double a = 2.1589687489;
String^ b = Convert::ToString(a);
b = b->remove(b->IndexOf('.')+2 );
}

There is no need to do that when you can use format strings to produce the required result in the first place.
