javascript中的数字非常大 [英] Extremely large numbers in javascript

问题描述

我正在研究Project Euler问题（目前问题13 ）。

I'm working on the Project Euler problems (currently question 13).

对于这个问题，我必须找到100个数字之和的前10位数，所有数字都与此类似：

For this question I have to find the first 10 digits of the sum of 100 numbers all of a size similar to this:

91,942,213,363,574,161,572,522,430,563,301,811,072,406,154,908,250

我想我可以使用类似Java的BigInteger，但我开始用JavaScript解决问题（我正在努力提高我的js工作能力），我想继续使用它，甚至解决这个问题。

I think I could use something like Java's BigInteger, but I started solving the problems in JavaScript (I'm trying to boost my js abilities for work), and I would like to continue using it, even to solve this problem.

如果可能，我想坚持使用纯粹的JS。

I'd like to stick to pure JS if possible.

推荐答案

您将需要一个基于javascript的BigInteger库。有很多可供选择。这是一个 https://github.com/peterolson/BigInteger.js

You are going to need a javascript based BigInteger library. There are many to choose from. Here is one https://github.com/peterolson/BigInteger.js

您可以像这样使用

var n = bigInt("91942213363574161572522430563301811072406154908250")
    .plus("91942213363574161572522430563301811072406154908250");
