- fixes #16011 # Description `Display` implementation for `f64` omits the decimal part for round numbers, and by using it we did the same. This affected: - conversions to delimited formats: `csv`, `tsv` - textual formats: `html`, `md`, `text` - pretty printed `json` (`--raw` was unaffected) - how single float values are displayed in the REPL > [!TIP] > This PR fixes our existing json pretty printing implementation. > We can likely switch to using serde_json's impl using its PrettyFormatter which allows arbitrary indent strings. # User-Facing Changes - Round trips through `csv`, `tsv`, and `json` preserve the type of round floats. - It's always clear whether a number is an integer or a float in the REPL ```nushell 4 / 2 # => 2 # before: is this an int or a float? 4 / 2 # => 2.0 # after: clearly a float ``` # Tests + Formatting Adjusted tests for the new behavior. - 🟢 toolkit fmt - 🟢 toolkit clippy - 🟢 toolkit test - 🟢 toolkit test stdlib # After Submitting N/A --------- Co-authored-by: Bahex <17417311+Bahex@users.noreply.github.com>
