Easy Q: 0.0 --> Output as string?

Hi all,

I'm trying to output 0.0 as a string ("0.0"). When I go: Math.Round(0.0,
2).ToString() it is outputting as 0.

Any ideas how to get the extra 0 after the decimal point?

Thanks.

Solved it... used Format instead. Format(0.0, "0.0")

One thing to be aware of (if not already), you'll get different results from
Format vs Round. "Round" uses bankers rounding (which makes no sense to me
<g>) while Format uses the same method of rounding I learned in math
class... which is, everything >=5 is rounded up.

Ken is correct. You can supply an overload to the Round method to force it
to behave the same as the format command. Use the MidpointRounding.AwayFromZero
overload. See my write-up at http://devauthority.com/blogs/jwooley/archive/2006/03/24/806.aspx.

Ah perfect - I like math rounding more ; )

How about this?

Math.Round(0.0, 2).ToString("0.0")

What is the data type of the value? If it is Decimal for example, you
can use this:

Decimal d = 0.0m;

MessageBox.Show(d.ToString("N1"); //Outputs 0.0
MessageBox.Show(d.ToString("C2"); //Outputs $0.00

It would help to know the context in which the value is used.

Oops! Forgot where I was:

Dim d As Decimal = 0.00

MessageBox.Show(d.ToString("N1")) 'Outputs 0.0
MessageBox.Show(d.ToString("C2")) 'Outputs $0.00
