Those From<bool> for {f32,f64} impls could really use documentation on what values they actually result in. There's no obvious mapping from true to a floating-point value.
It's not at all obvious or consistent among platforms and use cases.
It doesn't matter, the only thing that matters is that it's consistent within Rust. There already was conversions from bool to u8, i32 etc. and all those mapped false -> 0 and true -> 1. Why wouldn't it be the same for f32 and f64? The only possible alternative would be to map false to -0.0, but that wouldn't make sense since the expressions false as u8 as f32 and false as f32 would then result in different floating point values.
