Introduced in .NET 4.0 to support various functional and dynamic languages, the
BigInteger type provides unlimited-precision integral value math. Internally, it’s based on bit-vectors on which operations are done by turning those into basic math operations that the processor supports, including 32-bit and 64-bit arithmetic as well as bit-level operations. Luckily, all of this plumbing is nicely abstracted away from the user, and thanks to rich operator overloading the use of
BigInteger is quite simple.
First of all, note that
BigInteger lives outside the triad of BCL assemblies, namely in the
System.Numerics assembly. The namespace listening to the same name as this assembly will have to be imported, ...
