How Can I Handle Extremely Large Integers in C#?

Conquering Large Integers in C#

C# developers often face limitations when working with extremely large integer values. Standard data types like ulong fall short in terms of both range and performance. This article explores effective solutions for handling such numbers.

Efficient Approaches:

.NET Framework 4.0 and Later:

The built-in System.Numerics.BigInteger class, available from .NET 4.0 onwards, provides a robust and efficient way to perform arithmetic operations on integers of arbitrary size. Comprehensive documentation is available at: https://www.php.cn/link/afd208b1d98bc70e0aedc93bb4371c14

IntX Library: A Powerful Alternative

For a high-performance open-source solution, consider the IntX library. Written in C# 2.0, IntX boasts optimized multiplication and division algorithms (O(N*log N)), delivering significant speed improvements. It supports a wide range of integer operations, including addition, subtraction, multiplication, division, comparison, and bitwise manipulation.
