在javascript中尾随零 [英] Trailing zeros in javascript

问题描述

有没有办法在javascript中为一个数字添加尾随零？

Is there a way to add trailing zeros to a number in javascript?

例如：
47.0而不是47
或0.0而不是0

For example: 47.0 instead of 47 or 0.0 instead of 0

当我在json中返回数字时，零点消失器。

when I return the numbers in a json, the zeros disapper.

我需要它们是数字而不是字符串所以.toFixed（2）没有帮助。

I need them to be numbers and not strings so .toFixed(2) doesn't help.

谢谢！

推荐答案

没有。你想要的是一个特定的表示，大多数简单的类型没有概念。

No. What you want is a specific presentation, which most simple types has no concept of.

无论如何，当序列化为JSON请求或响应时，它仍然会被转换为字符串，但如果接收端表示为46.0,46.00或46.000，除非它周围有，否则接收端根本不在乎。

Anyway, when serialized into a JSON request or response it would still be converted to a string, but the receiving end shouldn't care at all if it's represented as 46.0, 46.00 or 46.000 unless it has the "" around it.
