This is awesome! Thank you for doing this so fast! 😄 Will this code work if the integer literal has underscores in it? What about negative numbers? The full spec of integer literals is here: https://doc.rust-lang.org/reference/tokens.html#integer-literals My personal opinion is that you don't need to support all forms of integers, but we should at least support literals in the format Thanks again! This seems like a small thing, but I think it's a big quality of life improvement for people who are new to Rust! 😃 |

@zackmdavis Please add tests for all cases that @sunjay gave. 😆 |
Sunjay Varma pointed out that this is a nice thing that we could do. Resolves rust-lang#53280.

It's nice to provide a bit of context in the comments without the need to open a browser :)
As a rule, I add a one sentence long description of what the code is doing (or rather, why), with the issue number at the end for extra context.

I agree that issue numbers are merely an extra reference for the curious software-archeologist and not a substitute for explanatory comments where explanatory comments are merited, but I feel like "use a float literal" is pretty self-explanatory? I do write explanatory comments where I think it necessary (recent examples: 1 2).
