What is the standard solution in JavaScript for handling big numbers (BigNum)?
提问by David Cary
Is there a bignum library for JavaScript or built-in that I can include like
是否有一个用于 JavaScript 或内置的 bignum 库，我可以包括
<script type="text/javascript" src="the_bignum_library.js"></script>
?
?
I think my users would prefer to enter numbers in a web page and wait 7 seconds for a result, rather than download an executable and click through a bunch of "this executable could possibly harm your computer" warning screens to install it.
我认为我的用户更愿意在网页中输入数字并等待 7 秒以获得结果，而不是下载可执行文件并单击一堆“此可执行文件可能会损害您的计算机”警告屏幕来安装它。
I've considered basing my own off of http://github.com/silentmatt/javascript-bigintegeror http://www.mainebrook.com/john/fun/euler.html. Or would you recommend calling from JavaScript into a Java bignum library such as apfloat?
我已经考虑过基于http://github.com/silentmatt/javascript-biginteger或http://www.mainebrook.com/john/fun/euler.html。或者你会推荐从 JavaScript 调用到 Java bignum 库，比如 apfloat？

Update(2019-08-19): BigIntis now part of Firefox and Chrome; you no longer need a library:
更新（2019-08-19）：BigInt现在是 Firefox 和 Chrome 的一部分；你不再需要图书馆：
const bigInt1 = 1111111111111111111111111111111n;
const bigInt2 = BigInt("1111111111111111111111111111111")
console.log((bigInt1 + bigInt2)+"")Original answer:
原答案：
If you need arbitrary-precision decimal numbers, use Javascript-bignum, as it is correct and fast.
如果您需要任意精度的十进制数，请使用Javascript-bignum，因为它正确且快速。
