How to handle big numbers in Javascript?

Question

I wanted to convert all my numbers to 4 fixed decimal points for that I am using toFixed()

 (1456.454534).toFixed()

But in my case I do have some number which are crossing the limit of MAX_SAFE_INTEGER like

11324237868788877767787.676886

In that case if I am using toFixed() it results into loss of precision.How can I handle this number?

Turn it into a string, then use your own parser or a library that handles it, probably — CertainPerformance

Depending on your JS environment and compatibility requirements, you may have the new BigInt type available.

If using only the latest and greatest isn't an option, there is at least one polyfill library out there

... or sure, you could represent it as a string as some commenters suggest, but it's awkward to do math with those strings.
