数字角度的错误计算 [英] Wrong calculations on number angular

问题描述

In angular 6 i am getting the invalid values when adding the large value numbers.

Is there any solution around this to handle large numbers for addition, comparison, etc?

我尝试过：

What I have tried:

9007199254740992==9007199254740993 
o/p = true

9007199254740992+0.98 
o/p = 9007199254740992

推荐答案

JavaScript中的数字不能任意大或精确 - 数字是64位值（基于IEEE 754标准），您已达到数字限制。您将不得不使用外部库，例如 bignumber.js [ ^ ]。

Numbers in JavaScript cannot be arbitrarily large or precise - numbers are 64-bit values (based on the IEEE 754 standard) and you've hit the limit with your number. You'll have to use an external library such as bignumber.js[^] for arbitrary precision.

这些是 JavaScript '功能'。您可能会在网上找到许多变通方法。例如，请参阅使用JavaScript中的大整数 [ ^ ]。

Those are JavaScript 'features'. You may find many workarounds on the web. See, for instance Working with large integers in JavaScript[^].
