Not only is BigInteger cool stuff, but also BigDecimal would be neat.

BigInteger support is used a bit and BCL support for complex numbers would save us the hassle of maintaining our own library. C++ stl now has complex support, and so does C99. At this point in time BigInteger and Complex support seem almost required for any framework.

I would just be happy if there was an INumeric interface so that we could actually use generics with numeric types.

This would be especially important for types like complex numbers, which depending on your needs might be decimal or double based.

I hope for real, deep numerical support. Maybe even things like interval arithmetic? :)

Importing J#'s BigInteger class is a workaround to for not having a BigInteger class in the .NET Framework. However, J#'s BigInteger class has a bug - The last time I checked, J# hangs on x.isProbablePrime(2) when x = new BigInteger ("117137"). Do you know if J#'s BigInteger class is working now or when it will be fixed?

Thank you.

And F# comes with its own BigInt etc. too.

For info, I have a stable, tested, and very efficient (i.e. fast) solution for this that works for both standard and existing types.

Hopefully the code should be freely released soon:

It's always better that you wait to do it right. I've seen quite a few items in the MS Connect/Feedback that were responded to with basically, "We reallize that this behavior is bad/poor/unintuitive, but we can't change it at this point without breaking applications that depend upon it." Good luck.

Update : BigInteger was cut from the .NET 3.5 release . Have you ever needed a really huge number? So
