如何在Node.js中进行64位整数运算？ [英] How to do 64bit Integer arithmetic in Node.js?
问题描述
任何人都有关于如何在Node.js中对64位整数执行算术的任何建议？ node-int64包似乎不支持它。
Anyone have any suggestions on how to perform arithmetic on 64bit integers in Node.js? The node-int64 package doesn't seem to support that.
推荐答案
Javascript不支持64位整数，因为本机数字类型是64位双精度，只有53位整数范围。
Javascript does not support 64 bit integers, because the native number type is a 64-bit double, giving only 53 bits of integer range.
您可以创建32位数字的数组（即 Uint32Array ）但是如果有64位数字那些版本的那些无法将值复制到独立变量中。
You can create arrays of 32-bit numbers (i.e. Uint32Array) but if there were a 64-bit version of those there'd be no way to copy values from it into standalone variables.
有一些模块可以提供64位整数支持：
There are some modules around to provide 64bit integer support:
- node-bigint
- bignum (based on OpenSSL)
- int64
也许您的问题可以使用其中一个库来解决。
Maybe your problem can be solved using one of those libraries.
