BigInteger Data Type In Framwork 4

While searching on the Internet and reading material regarding what is new in the framework 4 I come across the new data type which I have not see in the previous version of the dot net framework. The new data type is the BigInteger type. The BigInteger data type is used to store large amount of data. Like the other data type such as Int16, Int32 etc which has the MixValue and the MaxValue properties which define the lower bound and upper bound supported by that data type. In contrast, the BigInteger structure has no lower or upper bound, and can contain the value of any integer. The BigInteger data type is defined in the System.Numerics namespace. The System.Numerics namespace can be added as shown in the Image 1 as  System.Numerics is not added by default in the project you have to add the reference in your project.
