问题描述
在JSON网站此处上，它解释了JSON对象"的不同可能性.但是，在数字部分中，这些出现:
On the JSON website here, it explains the different possibilities of JSON 'objects'. However, in the numbers section, these appear:
e | e+ | e- | E | E+ | E-
e | e+ | e- | E | E+ | E-
1-这些代表什么?
在寻找答案时，<E>出现很多.
In searching for an answer, <E> appears alot.
2-<E>与上述e | E s相关吗?
2 - Is <E> related to the above e|Es?
推荐答案
这是JSON(和大多数编程语言)用于科学表示法的表示法.科学计数法用于表示非常大或很小的浮点数. e(或等效地E)等效于×10 ^".例如，
It's the notation JSON (and most programming languages) use for scientific notation. Scientific notation is used to denote very large or small floating-point numbers. The e (or equivalently E) is equivalent to "×10^". For example,
3.7e-5 = 3.7E-5 = 3.7×10 = 0.000037
3.7e-5 = 3.7E-5 = 3.7×10 = 0.000037
可以使用正或负指数，对于正指数，可以省略+符号:
Positive or negative exponents may be used, and in the case of positive exponents, the + symbol may be omitted:
6.02e+23 = 6.02e23 = 6.02×10 = 602六兆
6.02e+23 = 6.02e23 = 6.02×10 = 602 sextillion
