Formatting Numbers

I want to convert some decimal and floating point numbers to strings. I have been looking for examples of how to do this and came across the following posted example. It seems to be what I want, i.e., String^ out = i.ToString... However, when I run this example I get '02' on the screen, where I would like to see '05'. What am I missing

// example from another question //

using namespace System;

int main()
{
int i = 5;
Console::WriteLine(i.ToString()->Format("02"));
}

Hi,

Thanks Ayman Shoukry for moving this. Its your format string that causes the problem here. Try this instead:

using namespace System;

int main()
{
int i = 5;
Console::WriteLine(i.ToString()->Format("00"));
}

cheers,

Paul,

I tried going thru the referenced material, but I didn't really find what I wanted. I never saw anything similar to your use and I did't see any clear and simple example such as seems to exist with printf in the old books I have around. Can you or anyone else suggest a better, simpler reference

Gordon.

Hi,

Try this instead:

#include "stdafx.h"

using namespace System;

int main(array<System::String ^> ^args)
{
    int i = 5;
    Console::WriteLine(i.ToString("00"));
    Console::WriteLine(L"Hello World");
    return 0;
}

Here's a documentation on how to use the Format method of string class.

Paul,

Thanks. Your change worked. Where can I find the list of how Format parameters work

Here is the complete progam I ran (with a break at return so I could see the results). Here I got '00", not '05' So, what am I doing wrong    And, where do I find some good examples of what goes in the parameter list for Format

Gordon.

#include "stdafx.h"

using namespace System;

int main(array<System::String ^> ^args)
{
    int i = 5;
    Console::WriteLine(i.ToString()->Format("00"));
    Console::WriteLine(L"Hello World");
    return 0;
}

Moving to the .NET development forums since folks there should have more knowledge about the related issues.
