removing un-needed zeros from a number vb.net

mrobertson · 09-12-2005, 01:24 PM

I have an application that builds a string of numbers from a datagrid. the string will turn out to look something like this:

1234, 45.1250, 0.0899, 0.0135

Is there any way to remove the unneeded zero from the second number in the string. The zero may not always be in the same position.....it may look something like this 45.12560. Can anyone help me with this?

You could try:

Code:

Double.Parse(string).ToString()

That will give you back a string with trailing zeroes trimmed. It will not trim the leading zeroes of course, since it must be a valid number for the fuction to work.

EDIT: forgot () on ToString

I tried your suggestions and got an error saying :

Input string was not in the correct format

Do I need to add something else:

here is the code I use:

Code:

idRemovedStr = CompletedDataset.Tables("Table2").Rows(q).Item("Grade_Code") & "," & CompletedDataset.Tables("Table2").Rows(q).Item("Width") & "," & CompletedDataset.Tables("Table2").Rows(q).Item("Hot_Band_Gauge") & "," & CompletedDataset.Tables("Table2").Rows(q).Item("Target_Gauge")

Double.Parse(idRemovedStr).ToString()

Here is mine. It was tested and works fine. Just change it to fit your project:

Code:

 Label1.Text = (Double.Parse(txtInput.Text).ToString())

Sorry, just to clarify a little, this will need to be done for each string value you need to check, and returns only this single string value. That is, if your dataset contains three values, you will need to perform the function three times, adding each string to your comma separated string.
