Hi All,
I have one problem. I will be thankful for your help
I have one text box which accpts maximum 25 numeric digits and on lost event it is calculating and displaying the result in another text box
Private Sub Text1_LostFocus
Dim a as double
a=2
Text2.Text=Format(Text1.Text * Number2, "##############################")
End Sub

Now if I enter 999999999999999999999999999999 in text box and press tab key, it is showing 20000000000000000000000000 insted of 19999999999999999999999998.
Can anybody help me in this

This is a genaral problem. Double is a floating point data type and thus has a limited precision which you are exceeding. You are actually exceeding it with 999999999999999999999999999999 already. The value in the Textbox is a string, when implically casted to double (hard to calc with strings ) it already gets rounded to 1000000000000000000000000000000. If you really need integer math with such big numbers you need a seperate library like http://www.home.zonnet****/vspickelen...s/LargeInt.htm (haven't tried it myself)
