JavaScript中的尾随零

Question

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

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

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

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

Thanks!

Answer 1

数字47.0与47是相同的数字，因此更改其表示形式的唯一方法是使其成为字符串。

Answer 2

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

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.
