Is there a C# Equivalent to Java's BigDecimal Class?

What is an Equivalent of Java's BigDecimal Class in C#?

Question:

The java.math package in Java provides a BigDecimal class that facilitates the handling of большие числа with precision. Does C# offer a comparable class or data type?

Answer:

Recently, a developer encountered a similar need for an arbitrary precision decimal in C#. They sought a solution without relying on extensive external libraries.

A response emerged from the Stack Overflow community, outlining an approach to create a custom floating-point type in C#:

• Leverage the BigInteger class from .NET 4.0 to construct a mantissa with arbitrary size.
• Use an Int32 exponent with a base of 10 to represent the magnitude.

The implementation supports:

• Basic arithmetic and comparison operators
• Conversions to and from various numerical types
• Exponential methods

While not intended as a comprehensive solution, it proved functional and met the developer's requirements.

To access the implementation:

• Direct modification of the original response on Stack Overflow
• GitHub Gist: https://gist.github.com/JcBernack/0b4eef59ca97ee931a2f45542b9ff06d

The developer invites feedback, bug reports, and suggestions to enhance the solution.
