UOR Math-JS

A JavaScript library implementing the Prime Framework for universal number representation.

Overview

The Prime Math Library is a JavaScript library that implements the Prime Framework for numbers. It provides a comprehensive system for representing and manipulating integers in a base-independent way, ensuring unique, factorization-based representations and geometric consistency.

The library introduces Universal Numbers – integers encoded by their complete digit expansions across all bases – and supports operations on these numbers while preserving their intrinsic prime factor structure.

Installation

npm (Node.js)

# Install from GitHub Packages
npm install @uor-foundation/math-js

You may need to configure npm to use GitHub Packages by creating a .npmrc file in your project:

@uor-foundation:registry=https://npm.pkg.github.com

If you're using a private repository, you'll need to authenticate with GitHub Packages. See GitHub's documentation for more details.

Browser

You can include the library directly in your browser applications using the minified UMD bundle:

<!-- From your own server -->
<script src="path/to/math-js.min.js"></script>

<!-- Or from GitHub (replace 'main' with a specific tag or commit if needed) -->
<script src="https://raw.githubusercontent.com/uor-foundation/math-js/main/dist/math-js.min.js"></script>

<script>
  // The library is available as the global variable 'PrimeMath'
  const { UniversalNumber } = PrimeMath;
  
  const num = UniversalNumber.fromNumber(42);
  console.log(num.toString());
</script>

Basic Usage

const { UniversalNumber, PrimeMath } = require('@uor-foundation/math-js');

// Create universal numbers
const a = UniversalNumber.fromNumber(42);
const b = UniversalNumber.fromString("123456789");

// Perform arithmetic operations
const sum = a.add(b);
const product = a.multiply(b);

// Get the prime factorization
const factors = a.getCoordinates();
console.log(factors); // Array of prime-exponent pairs

// Check if a number is an intrinsic prime
const isPrime = b.isIntrinsicPrime();

// Convert back to standard formats
const bigIntValue = sum.toBigInt();
const decimalString = product.toString();

Features

  • Universal Number Representation: Numbers are stored in their unique canonical form via prime factorization
  • Exact Arithmetic: Guaranteed lossless operations, preserving full precision
  • Base-Independent: Work with numbers in their intrinsic form, not tied to any specific base
  • Seamless Conversions: Convert between universal representation and standard formats
  • Number Theory Operations: Access to prime factorization, GCD, LCM, and primality testing
  • Global Configuration: Centralized system to control memory usage, computation limits, and performance trade-offs

Configuration

The library includes a comprehensive configuration system that allows you to adjust memory usage, computation limits, and performance trade-offs:

const math = require('@uor-foundation/math-js');

// Configure the library according to your needs
math.configure({
  performanceProfile: 'speed',  // Options: 'balanced', 'speed', or 'precision'
  cache: {
    maxPrimeCacheSize: 50000,
    maxFactorizationCacheSize: 1000
  },
  factorization: {
    completeSizeLimit: 150  // Maximum digit size for complete factorization
  }
});

For more details, see Configuration Guide.

Documentation

For full API documentation, run:

npm run docs

Then open docs/generated/index.html in your browser.

Performance Benchmarking

The library includes a comprehensive benchmarking system to measure and optimize performance. To run benchmarks:

# Run all benchmarks
npm run benchmark

# Run with garbage collection for more accurate memory measurements
npm run benchmark:gc
