Introduction

HigginsSoft.Math is a free DotNet library inspired by GmpLib, Yafu, GGNFS, and other libraries that aims to bring high-performance artihmetic and number theory operations to the DotNet world.

It offers specific implemenations as well as wrappers for some of those libraries so they can be used in DotNet as any other type would be without worrying about the underlying low-level implemtations of those libaries.

Usage

To use HigginsSoft.Math, simply reference the HigginsSoft.Math namespace in your code and use the available functions.

Wrappers for GmpLib's mpz_t (multi-precision integer) is available as GmpInt while the mpz_f (multi-precision float) is available as GmpFloat.

Both wrappers have the standard artithmetic, binary, compare and cast operators built-in for implicit/explicit conversion with the built-in DotNet numeric data types, including System.Numerics.BigInteger

    GmpInt a = 1;
    GmpInt b = a << 80;
    BigInteger check = BigInteger.Power(2, 80);
    Assert.IsTrue(() => b == check);
    GmpInt c = check;
    Assert.IsTrue(() => c == check);

Overview

GmpInt and GmpFloat

Cast Operators:

• Implicit cast operators are defined for all integer based system types including byte, sbyte, int, unit, long, ulong, BigInteger, as well string as well as the GmpInt and mpz_t types.
• Explicit cast operators are defined for all decimal types system types including float, double, and decimal, as well as the GmpFloat and mpz_f types
• Constructors exist in both GmpInt and GmpFloat for the system types.

Note: The explicit operators will truncate the decimal types which could lead to unexpected results, so take care when converting between the types.

Comparison Operators:

• The standard comparison operators (<, <=, ==, !=, >, >=, and >) and CompareTo are defined for the GmpInt and GmpFloat types and all corresponding system numeric types.

Arithmetic Operators:

• The standard binary arithemtic operators (+, -, *, /, %, --, ++) as well as unary operators (+, -') are defined for the GmpInt and GmpFloat types.

Binary Operators:

• The standard binary operators (^, ~, and xor) are defined for the GmpInt and GmpFloat types.

Named Methods:

The following named methods are available, many with various overloads:

Low-level GMP functions.

While the GmpInt and GmpFloat types offer a fully managed native DotNet experience without the need to worry about managing unsafe types low-level GMP functions are available to throw using gmp_lib by importing MathGmp.Native which the libary currently uses for access to the native GMP library.

Prime Generation:

A PrimeGenerator can be used to generate a list of primes. The default constructor will generate all primes starting from 2. You can also use the constructor overload to specify a starting and/or maximum prime.

The generator is able to produce all primes up to 2^31 in ~.5 seconds when ran in parallel mode using HigginsSoft.DotMpi to launch multi-processor sieving threads.

Using the uint data type has a sligh performance hit but the generator can produce all primes up to 2^32 in a little over 1 second.
