Did you consider "whose range is {}..={}"? That style is less verbose and easier for me to parse.
Also, a small nit, I would not say "an u16". Is there a way to phrase the message without an indefinite article?

@ecstatic-morse I agree. This seems like an improvement, but not a fix for that issue. |

You can use chaining here.

I am not sure what is a typo. What I intended to do is adding more context for f64 overflow.

The "as it is represents infinity" part does not make sense to me. Does it mean the following?
Suggested change
| "the literal `{}` does not fit into type `{}` as it is represents infinity", | |
| "the literal `{}` does not fit into type `{}` and will be converted to `std::{}::INFINITY`", |

Nice catch. Your error message is much more informative. Thanks. I will update it presently.

Since the range is a valid rust expression, I would write it in backticks.
Suggested change
| "the literal `{}` does not fit into type `{}` whose range is {}..={}", | |
| "the literal `{}` does not fit into the type `{}`, whose range is `{}..={}`", |
