Also update to use https instead of http. This avois mixed content
degradation on docs.rs.
The doc root URLs are correct as they are, the URL does not include the
crate name itself.
To avoid a breaking change, these have crude default implementations as
well as better implementations for `f32` and `f64` in particular. They
don't use the inherent methods though, because `f32` didn't stabilize
those until Rust 1.7.
Fixes#211
It should use the destination type and not the source type to check if
the conversion would be to a value that's in range.
NOTE: A finite f64 value that is larger than the f32 value range now produces
None when converted to f32 with ToPrimitive.
Previously, too large f64 values would produce inf f32 values. This `as`
cast has an undefined result and was not specified to always produce for
example `inf`.
The conversion preserves nan/+-inf specifically.
For some reason, rustc 1.0.0 can't find `PrimInt` if it's before `cast`,
but later versions are fine with this. That may have been a compiler
bug that was fixed. Switching the order seems to work everywhere.
