Thanks so much for this @animeshsrivastava24. It's very well written but I have a couple of requests to improve the structure of the page:

Move detailed information to the "Notes and Warnings" section

• The Description section of a reference page should contain a beginner friendly description. More advanced details should be added to a Notes and Warnings section near the bottom of the page so that beginners won't be overwhelmed with information before they reach the Syntax/Parameters and Example Code sections. The float reference page was already a bit heavy on complex details in the Description section and the information you added makes it far too long.

Please move all the description text from "Floats have only 6-7 decimal digits of precision." onward to a Notes and Warnings section. You can see an example of a Notes and Warnings section in this page:
https://github.com/arduino/reference-en/blob/master/Language/Functions/Math/constrain.adoc

Don't create multiple Example Code sections

The reference page should only contain a single Example Code section. The code examples you have added are great and should be in code blocks, but you should not create an Example Code section for each of them.

---

Once those changes are made, I'll look over the PR again to see if I maybe have a few other small requests to make but it's better that these larger structural changes are made first.

@animeshsrivastava24 why did you close this? I think it is a very useful and needed pull request. I only am hoping you could make some modifications to the formatting of it as I described above.

[animeshsrivastava24]

@per1234 Definitely, I will make the modifications and format it. Sorry, for the inconvenience caused.
