Unable to use System.Numeric in Xamarin studio c#

Question

I am writing a console project which requires some very large numbers above the limit of all classes in c#. I have read of a biginteger class which can support this. Despite this my c# compiler does not recognise the use of System.Numeric which is required to use the biginteger class. I am aware of and able to implement a work around using arrays to store the digits but this would be messier and I was wondering if there was an easier way to use this class somehow.

Answer 1

Add a reference to System.Numerics in your console project:

Then include:

using System.Numerics;

Usage:

var bInt = new BigInteger();

How do I get to this window?

To access the project's references, double click on the "References" item within your Solution/Project sub-tree.
