How Can I Efficiently Handle Big Integers in C#?

Optimizing Big Integer Operations in C#

Working with extremely large integers in C# can impact performance. Using java.math.BigInteger (often accessed via J# libraries) can lead to significant slowdowns.

However, superior alternatives exist within the C# ecosystem. The built-in System.Numerics.BigInteger class (introduced in .NET 4.0) offers a considerable performance boost compared to J# alternatives, supporting a full range of arithmetic operations.

For even more demanding applications, consider the open-source IntX library. IntX employs optimized algorithms (O(N * log N) for multiplication and division), resulting in faster processing of large numbers. It also offers a comprehensive set of integer functions.

Both System.Numerics.BigInteger and IntX provide substantial performance improvements over J# based solutions, enabling efficient handling of big integers without compromising speed.
