/stdlib update-copyright-years

should I change it to 2024 ?

@Pushpendra766 The /stdlib update-copyright-years command automatically has our stdlib-bot update the copyright years for added files, see: 5c3356e. Just pull down the changes, no reason for you to manually change them.

Okay, thanks.
I have done the suggested changes. I hope it will fix the formatting and documentation issues.

CI is currently failing, please take a look. I think the manifest.json file is missing used packages in the examples and benchmark configurations, namely random/base/randu, but looks like we also have a problem with the implementation since the tests fail, although at first glance, it looks fine to me and matching the JS implementation.

random/base/randu is not a dependency for atan2, as far as I know.
Also, I checked the implementation thoroughly. It matches the JavaScript implementation of the function.

Tested locally, everything works well. Thanks @Pushpendra766 !
