Mostly related to the `us` → `usize` suffix renaming. It turns out that none of
the suffixes are required any more, as the type inference appears to have
improved in that regard. There were also parantheses around range terms that
are not required any more.
Finally the `[]` syntax has been deprecated and thereby removed.
Fixes#52.
This renames pairs of methods like `normalize_cpy`, `normalize` to `normalize`
and `normalize_mut`. Note that the previous in-place operations had the same
name that now belongs to the copy operations. Therefore this is a breaking
change.
On a similar note, the `Quat::conjugate` method was also renamed to
`conjugate_mut` and a new copying method has taken its place. This appears to
be a similar issue (apart from the lack of the copy operation) and thus was
dealt with here, too.
Just as the standard library's PartialEq is implemented for reference types,
the ApproxEq trait should be implemented on them as well. This is mostly an
ergonomic improvement for certain testing situations, where a method yields a
reference. For non-copy types it allows using the assert_approx_… macros, which
would otherwise not be possible.
Rot4 and Iso4 had to be left out, since Rot4 apparently lacks a working
constructor.
Thereby (almost) all types in nalgebra can now be used for quickcheck-style
testing.
"arbitrary" is now a conditionally compiled feature that contains these impls
adding a dependency on quickcheck.
approx_eq_ulps() allows specification of epsilon as an integer number
of Units in the Last Place (ULPs) difference between the two floating
point values
default approx_ulps() is set to 8.
approx_eq() function continues to use epsilon method, although I
recommend further commits and a migration towards the ULPs method.
Wherever sensible the geometric traits now take `&self` arguments, so that
implementations can be invoked as instance methods instead of static methods.
This makes some idioms easier to express and generally allows for greater
flexibility as the restructured methods can still be invoked like static
methods.
Fixes#39.
