Stupid q for the day, but if the user enters 2 in a textbox, I want to
display as 2.00.
If they enter 2.129 I want it as 2.13.
I'm guessing will code in the validated method of the textbox, but not sure
how to convert the number.
Thanks for the help. 3 12338

Hi Ronald,
Would something like the following work for you?
protected void Button1_Click(o bject sender, EventArgs e)
{
double d;
if(double.TryPa rse(TextBox1.Te xt, out d))
{
d = Math.Round(d, 2);
Label1.Text = string.Format(" {0:.00}", d);
}
}
Also I've posted a link below that has helped me alot with string
formatting http://blog.stevex.net/index.php/str...ing-in-csharp/
Happy coding!
There are couple of ways doing it...
Use Key_Press event as below on the textbox
private void textBox1_KeyPre ss(object sender, KeyPressEventAr gs e)
{
if(! (char.IsDigit(e .KeyChar) || e.KeyChar == '.') ) //
use the keys that you want to handle
{
e.Handled = true;
}
}
and also textbox validation event as below
private void textBox1_Valida ted(object sender, EventArgs e)
{
double d;
if(double.TryPa rse(textBox1.Te xt,out d))
{
d = Math.Round(d,2) ;
textBox1.Text = d.ToString();
}
}
This should solve the problem.
However I would like to derive a class from Textbox and handle the
above events in the derived class and use the same on the form. This
will give you flexibility in the future.

if(! (char.IsDigit(e .KeyChar) || e.KeyChar == '.') ) //
But what's with country where number separator is "," not "." like
Poland?
I don't think it is the best resolution.

I want to output a number, say 20, as 20.00

Can't seem to find a way to do this. Any ideas?

Stupid question for the day but weirdly I don't have this yet.
How can I format a textbox such that if the user enters a number like 4 it
will become (on validated) 4.00.
If they enter 5.1 it will become 5.10.
If they enter 1.239 it will become 1.24.
Thanks for the help.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
