Hi,

read here:

The code should be something like:

string strd = "-6.355410929135618578000000000000000000000e+83";
NumberStyles styles;
styles = NumberStyles.AllowExponent | NumberStyles.Number;
double dbl = Double.Parse(strd, styles);

hi,
Thanks so much,
i have tried with below example as per your idea but i am still getting the result with E+83. how i can resolve this and how i remove the E values

string strd = "-6.355410929135618578000000000000000000000e+83";
NumberStyles styles;
styles = NumberStyles.AllowExponent | NumberStyles.Number;
double dbl1 = Double.Parse(strd, styles);
double dbl2 = Double.parse("149.0922279000",styles);
double Total = dbl1 + dbl2;

Thanks

What do you mean by: "remove the E values"? - Has the value you are reading from the xml file the wrong value, or has it just not the format you want it to be?

yes, i am reading the two values from the XML file.
First value is "-6.355410929135618578000000000000000000000e+83" in string format.
Second value is "149.0922279000" in string format.
I have to add these two values first.This is my first step from the logic what I have.
While adding this two values,I am getting the result is "-6.3554109291356186E+83".
Here i need some value like "-x.xxxxxxxxx" and not like "-x.xxxxxxxE+18".
How i can convert.
Is My Question is clear ? please advice me

No, your question is not clear. If you add both of these values, it is pretty clear, that the result you get is: xxxE+xxx. You could only format the xxxE+xxx value when displaying to the user to be displayed as xxxxxxxxx.xxxxx
