HighPrecisionMath

HighPrecisionMath is a lightweight, high-precision arithmetic library for .NET, providing a RationalNumber type built on BigInteger. It allows exact fractional calculations, avoiding the precision issues of standard floating-point and decimal types.

Features

Arbitrary-precision rational numbers using BigInteger.

Fractional arithmetic: addition, subtraction, multiplication, division.

Comparison operators: <, >, ⇐, >=, ==, !=.

Conversion to decimal with configurable precision.

Optional exact fraction display (numerator/denominator).

Predefined constants like Zero, One, and high-precision approximation of Pi.

Unit tests with xUnit for reliability.

Designed for both scientific calculations and financial applications.

Installation

Clone the repository:

git clone https://github.com/cmk1988/HighPrecisionMath.git

Or include it as a submodule in your project:

git submodule add https://github.com/cmk1988/HighPrecisionMath.git

Usage

Creating Rational Numbers using HighPrecisionMath; using System.Numerics;

// Using integers var a = new RationalNumber(1, 2); // 1/2 var b = new RationalNumber(3, 4); // 3/4

// Using decimals var c = new RationalNumber(0.75m); // 3/4

Arithmetic

var sum = a + b; // 5/4 var diff = b - a; // 1/4 var product = a * b; // 3/8 var quotient = a / b; // 2/3

Comparison

if (a < b) { /* ... / } if (b >= a) { / ... */ }

Conversion

decimal value = sum.Value; // Approximate decimal value string fraction = sum.ToString(true); // Exact fraction "5/4"

Constants

var zero = RationalNumber.Zero; var one = RationalNumber.One; var pi = RationalNumber.Pi(); // High-precision approximation

Testing

Unit tests are implemented with xUnit. To run tests:

dotnet test

Tests cover arithmetic, comparison, conversion, and edge cases.
