Append .0 to unsuffixed float if it would otherwise become int token Previously the unsuffixed f32/f64 constructors of `proc_macro::Literal` would create literal tokens that are definitely not a float: ```rust Literal::f32_unsuffixed(10.0) // 10 Literal::f32_suffixed(10.0) // 10f32 Literal::f64_unsuffixed(10.0) // 10 Literal::f64_suffixed(10.0) // 10f64 ``` Notice that the `10` are actually integer tokens if you were to reparse them, not float tokens. This diff updates `Literal::f32_unsuffixed` and `Literal::f64_unsuffixed` to produce tokens that unambiguously parse as a float. This matches longstanding behavior of the proc-macro2 crate's implementation of these APIs dating back at least 3.5 years, so it's likely an unobjectionable behavior. ```rust Literal::f32_unsuffixed(10.0) // 10.0 Literal::f32_suffixed(10.0) // 10f32 Literal::f64_unsuffixed(10.0) // 10.0 Literal::f64_suffixed(10.0) // 10f64 ``` Fixes https://github.com/dtolnay/syn/issues/1085. |
