just learning and having trouble with DOUBLE and Text display

[Mark Reed]

Im just learning C#, and am trying to get a button click to generate and
display the total plus 10%.

I am doing the following, and it works, but does not display to two
decimal places, it goes out to many more. I thought by using DOUBLE, it
would limit it to two places.

Any ideas what I am doing wrong?
private void button1_Click(object sender, System.EventArgs e)
{
double tenper = (float.Parse(tbCheck.Text)*1.10);
label2.Text = tenper.ToString();
}

Hi Mark,

Try changing your call to ToString using ToString("N") or ToString("N2").

Thanks.

Shortly after posting, I came across th MSDN section that had me
working.

I am curious though, why it does not work as I had it... in theory,
would not the DOUBLE force the tenper variable to be two decimals? Then
when I make the textbox equal to the variable, why would it not be what
the DOUBLE set it to?

Please note that "double" here does not mean 2 decimal places, instead it
means "double precision floating point number". Therefore you should
specify the format of your output in your statement that really suits you.

Mark,

Is it not the decimal that you need?
