PHP 的大数库。

为开发者设置

只需克隆项目，进入项目目录并运行 composer install 即可。另外，为了运行测试，你应该执行 vendor/phpunit/phpunit/phpunit tests/。

安装

该软件包可以通过 composer require hpez/php-bignum 或 packagist 仓库 安装。

用法

<?php

// BigInteger Addition
$bigInt1 = new BigInt('123456')
$bigInt2 = new BigInt('654321');
$bigInt1->add($bigInt2);
echo $bigInt1; // "777777"

// BigFloat Addition

// BigInteger Modulo
$bigInt9 = new BigInt('777777');

echo $bigInt9; // "123456"

// BigInteger Power

// BigInteger Square Root
$bigInt14 = new BigInt('10000');

echo $bigInt14; // "100"

// BigFloat Square Root
$bigFloat10 = new BigFloat('2');
$bigFloat11->sqrt(7);
echo $bigFloat10; // "1.4142136"

// BigInteger Lesser-Than
$bigInt16 = new BigInt('1234567890');
$bigInt17 = new BigInt('1234567891');
echo $bigInt16->isLesserThan($bigInt17); // True

$bigInt18 = new BigInt('1234567891');
$bigInt19 = new BigInt('1234567891');
echo $bigInt18->isLesserThan($bigInt19); // False

// BigInteger Bigger-Than
$bigInt20 = new BigInt('1234567891');
$bigInt21 = new BigInt('1234567890');
echo $bigInt20->isBiggerThan($bigInt21); // True

$bigInt22 = new BigInt('1234567891');
$bigInt23 = new BigInt('1234567891');
echo $bigInt22->isBiggerThan($bigInt23); // False

路线图

此项目的目标是创建一个完整的大数库，因此除了表中提到的操作外，还应添加其他操作（三角函数等）。
