What should I use for a BigInt class in .NET?

Question

Until BCL finally ships System.Numeric.BigInt, what do you guys use for arbitrary precision integers?

Answer 1

You could try mine on codeplex: BigInteger

Or here's another: codeproject

Answer 2

F# has Microsoft.FSharp.Math.BigInt and Microsoft.FSharp.Math.BigNum.

Answer 3

Also, the J# library includes a BigInt type.

Thankfully, all this will be sorted out when the BCL finally ships a standardized BigInt.

UPDATE 2012 System.Numberics.BigInteger is now included in the .NET framework.

Answer 4

Have a look at

IronRuby.StandardLibrary.BigDecimal.BigDecimal
