.NET Framework Library for arbitrary digit precision

Question

I\'m reviving this question, and making it more specific: Is there a .NET framework library that supports numbers with arbitrary digits of precision?

Answer 1

You could try the old method of mantissa. Basically you could have an 64 bit integer for storing the number and then a 64 bit integer for storing the exponent (which could be negative). You could build your own object type and overload the arithmetic operators, so it will be treated as a single number. It will require some work, but I think it will be your best option.
