MissingValues 1.2.1

MissingValues numeric library for .Net 7+

MissingValues is a C# numeric library for C# that introduces support for large integers and higher precision floating-point numbers. It supports .Net 7 Generic Math.

Features

256-Bit and 512-Bit Integers

The library implements 256-bit and 512-bit integers, for both signed (Int256/Int512) and unsigned (UInt256/UInt512) integer arithmetic operations.

Here is a chart comparing the existing binary integers to the MissingValues integers:

Example Usage

using MissingValues; // namespace

// You can use the constructor:
Int256 num1 = new Int256(0x8000_0000_0000_0000, 0x0000_0000_0000_0000, 0x0000_0000_0000_0000, 0x0000_0000_0000_0001);
// You can use Parse():
Int256 num2 = Int256.Parse("10000000000000000000000000000000000000000000000000000000000000000000000000000");
// Or you can convert any other number type:
Int256 num3 = long.MaxValue;

// sum = -57896044618658097711785492504343953926634992332820282019728792003956564819967 + 10000000000000000000000000000000000000000000000000000000000000000000000000000 + 9223372036854775807
Int256 sum = num1 + num2 + num3;

Console.WriteLine($"Sum: {sum}");

// Prints: -47896044618658097711785492504343953926634992332820282019719568631919710044160

Quadruple-Precision Floating-Point Number

The library introduces the Quad struct, representing a quadruple-precision floating-point number. Quadruple-precision offers higher precision than standard double or float types, making it suitable for applications requiring extensive precision in numerical calculations.

Here is a chart comparing the existing IEEE floating point numbers to Quad:

Example Usage

using MissingValues; // namespace

// You can use the constructor:
Quad num1 = new Quad(sign: false, exp: 0x4004, sig: new UInt128(0x0000_9400_0000_0000, 0x0000_0000_0000_0000));
// You can use Parse():
Quad num2 = Quad.Parse("2e24");
// Or you can convert any other number type:
Quad num3 = 12.25d;

// sum = 50,5 + 2000000000000000000000000 + 12,25
Quad sum = num1 + num2 + num3;

Console.WriteLine($"Sum: {sum}");

// Prints 2000000000000000000000062,75
