Is there a JVM implementation of the JavaScript Number.toString() method somewhere? (see https://youtrack.jetbrains.com/issue/KT-33358). I need to write some JVM code that maps 1:1 with some JS code.

[ephemient]

JS Number.toString is partly implementation-defined, not standardized: https://tc39.es/ecma262/multipage/numbers-and-dates.html#sec-number.prototype.tostring

Yikes

Thanks for the pointer though 💙 !

I guess a "NodeJS" version would fit my needs for the time being if there such a thing

[mbonnin]

But since it's not standardized, I guess it's not something I can find "on the shelf" easily

[ephemient]

node.js behavior is effectively v8 (except for the chakracore version but I don't think anybody is using that anymore)

[ephemient]

v8 behavior isn't necessarily fixed; http://code.google.com/p/v8/issues/detail?id=1627

[ephemient]

but it's currently https://chromium.googlesource.com/v8/v8/+/refs/heads/main/src/numbers/conversions.cc

[ephemient]

hey you may be in luck, it looks like Rhino ported V8's algorithm, https://github.com/mozilla/rhino/tree/master/src/org/mozilla/javascript/v8dtoa

Oohhh Thanks! Will look into this!
