Question

i have an account number that is stored in as a query string. How do i convert 6.21129e+006 into an actual int

Answer 1

You can parse the string as a double, and later cast the double to integer.

However, casting from double to integer is subject to precision lost or even integer overflow

string s = "6.21129e+006";
double d = Double.Parse(s);
Console.WriteLine(s);

int i = (int)d;
Console.WriteLine(i);
