推荐答案
一个20位的数字通常也是如此对于JavaScript本机数字类型来说很重要,因此您需要找到要使用的大数字包。这是我在Stack Overflow上看到过的一个看起来很有趣的内容: http://silentmatt.com/biginteger/
A 20-digit number is generally too big for a JavaScript native numeric type, so you'll need to find a "big number" package to use. Here's one that I've seen mentioned on Stack Overflow and that looks interesting: http://silentmatt.com/biginteger/
那只是整数。如果你也需要小数分数,你必须找到别的东西。
That one is just integers. If you need decimal fractions too, you'll have to find something else.
如果你只是想检查一个20位数的字符串是什么样的一个数字,你不需要知道这个值,你可以用正则表达式来做。
If you just want to check that a 20-digit string looks like a number, and you don't need to know the value, you can do that with a regular expression.
