JSON中的Infinity是否比1e309更简洁？ [英] Is there is a more concise representation of Infinity in JSON than 1e309?

问题描述

JSON RFC（

ietf.org/html/rfc4627rel =nofollow> http://tools.ietf.org/html/rfc4627 ）指出NaN，Positive Infinity和Negative Infinity不能用JSON表示：

不允许以数字序列（例如Infinity和NaN）表示的数字值。

我不知道从哪里得到1 * 10 ^ 309，因为Javascript的最大确切整数值是2 ^ 53。

当你说简洁时，你的意思是简洁吗？

It's the smallest I could find.

解决方案

The JSON RFC ( http://tools.ietf.org/html/rfc4627 ) states that NaN, Positive Infinity and Negative Infinity cannot be represented in JSON:

Numeric values that cannot be represented as sequences of digits (such as Infinity and NaN) are not permitted.

I don't know where you're getting 1*10^309 from, because Javascript's maximum exact integer value is 2^53.

When you say "concise" do you actually mean "succinct"?
