In other applications, you don't care about exact results, but you are interested in having an answer that is correct to a certain number of significant digits. This is the case in experimental physics, for example. When you make a measurement of something, you can only measure it as accurately as your equipment will allow you. Therefore, you have an inherent error in that value already, which is going to cascade through any calculations you do with it. This means that while your computed answer may be 5.1826, you may know that the values this answer was calculated from were only accurate to three significant digits, and so the last two digits in this result (the 0.0026) don't matter. If there is a computational error in them, so be it - it's not going to hurt us.
A cookie is a small amount of data which is either stored at client side in text file or in memory of the client browser session. Cookies are always sent with the request to the web server and information can be retrieved from the cookies at the web server. In ASP.Net, HttpRequest object contains cookies collection which is nothing but list of HttpCookie objects. Cookies are generally used for tracking the user/request in ASP.Net for example, ASP.Net internally uses cookie to store session identifier to know whether request is coming from same client or not. We can also store some information like user identifier (UserName/Nick Name etc) in the cookies and retrieve them when any request is made to the web server as described in following example. It should be noted that cookies are generally used for storing only small amount of data(i.e 1-10 KB)
