Zitat von MSDN:

[cite]Does the .NET Framework support big numbers??
By big number, it is assumed what is required is a number with an unbounded level of precision, or for practical purposes, one that is only bounded by available memory.
The Decimal class is the closest thing to a big number in the .NET Framework in V1.0 and V1.1. It supports 96 bits of precision and 16 bits of scaling.

There is no big number type in V1.0 or V1.1, and there is no announced support in the Visual Studio 2005 (Whidbey) pre-releases. There is a reasonable amount of interest in such a type, so it is conceivable that it will appear in future versions, but it is not a small amount of work. [/cite]
