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!

• javascript
• json
• node.js

• 2 Numbers (aka IEEE754 Doubles) are represented in binary exponential notation. They can not have trailing (or leading... or whatever) zeroes. – Vatev Commented Nov 12, 2013 at 19:23
• So you take the string and convert them to numbers when you need to perform an operation with them. – epascarello Commented Nov 12, 2013 at 19:42

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.

The number 47.0 is the same number as 47, so the only way to change its representation is to make it a string.
