Add `// run-pass` annotations to all the tests under `ui/run-pass/`. (I may have accidentally added it to some auxilliary crates as well; my emacs-macro-based methodology was pretty crude.) 2018-08-30 07:18:55 -05:00			`// run-pass`

Remove re-exports of std::io::stdio::{print, println} in the prelude. The `print!` and `println!` macros are now the preferred method of printing, and so there is no reason to export the `stdio` functions in the prelude. The functions have also been replaced by their macro counterparts in the tutorial and other documentation so that newcomers don't get confused about what they should be using. 2014-01-09 04:06:55 -06:00			`println!("{}", x);`
remove the `float` type It is simply defined as `f64` across every platform right now. A use case hasn't been presented for a `float` type defined as the highest precision floating point type implemented in hardware on the platform. Performance-wise, using the smallest precision correct for the use case greatly saves on cache space and allows for fitting more numbers into SSE/AVX registers. If there was a use case, this could be implemented as simply a type alias or a struct thanks to `#[cfg(...)]`.
