i am on a visual studio 2010 , working on a visual basics windows application project

in my project i have to compute with very large numbers like 2790 to the power 2753
i tried Math.pow function but it could not compute it

i also tried to do it in a loop with int32 , int64 , decimal , long , Ulong data types but non could do it

but my windows calculator can compute it , means my PC is able to compute it but my program is not

so how can i do the power function ?

Solution 1

You should use BigInteger[^] for such a situation.

In this scenario use : BigInteger.Pow Method[^]

You'll have to add a reference of System.Numerics.dll. Then only you'll able to use C# BigInteger.

Solution 2

As an alternative to the proposed CodeProject's article, you may also have a look at the very .NET Framework's BigInteger class[^].
