One of the simplest and fascinating aspects of math is the number PI . Described simply as the ratio of a circle’s circumference to its diameter, it’s a constant with infinite digits after the decimal point and most importantly, non repeating (at least as far as I know).

One of the simplest new additions to the .NET 4.0 framework is an integer with arbitrary length, System.Numerics.BigInteger . Here’s a simple usage example, comparing it to a double:   BigInteger b = BigInteger . Pow (2, 64); Console . WriteLine ( "BigInteger: {0}" , b . ToString ( "N" )); Console . WriteLine ( "Double:     {0}" , Math . Pow (2, 64). ToString ( "N" )); Console . WriteLine (); b = BigInteger . Pow (2, 128); Console ...
