Follows (278), changes every float equality check that gets run by cargo test -p argmin-math.

Thanks a lot! :) I'll provide a review soon. I will fix the clippy lints in another PR and once that is merged you can rebase this PR. New Rust version, new clippy lints ;)

[stefan-k]

Looks great, I only have one minor request. Once this is addressed and #328 is merged you can rebase and this is good to go!

[stefan-k]

Thanks! Do you plan to make these changes also for the ndarray and nalgebra backends? You obviously don't have to, what you have done so far is already very helpful!

Apparently everything is falling apart. I fixed the broken website build in #329.

Good to know I'm helpful :) Not immediately at least, but maybe in the future.

LGTM. Thanks again! :)
