Backport 7088, BUG: Have norm cast non-floating point arrays to 64-bit float arrays

Related: #7088
Fixes: #5626

Backported from master to 1.11.x.

Simply ensures that non-floating type arrays passed to norm get cast to some form of float.

@charris, here is the backport of this PR ( #7088 ).

[charris]

Hmm, I just made one also but haven't pushed it. Could you fix up the commit messages as suggested in the previous #7088?

[jakirkham]

Is there a good way to tell vi to color code lines that go over some length? I feel like I will always miss this if it doesn't point it out to me.

[charris]

There probably is. I just do :set tw=72 and use gq on the selected text. Setting tw should also cause a wrap at the selected line length. I would be good to set that when git calls up the text editor, maybe there is a way to specify that.

[jakirkham]

Ok, thanks for the pointer. I think these are correct.

http://stackoverflow.com/questions/11023194/git-vim-automatically-wrap-long-commit-messages Looks like there is also a git.commit plugin.

[jakirkham]

Was just looking at that. Though my system vi is ancient so I don't know if they will play nice.

[jakirkham]

Managed to fixup vi. This is pretty slick. It just autowraps when writing a commit message. Also, it encourages you to keep a newline between your summary message and the body.

[charris]

You are having better luck than me. There must be a conflict somewhere in my vim configuration.

[jakirkham]

Looks like everything checks out.

[charris]

OK, thanks.

[jakirkham]

Sure. Did you ever git vim figured out?

This introduced a regression, see #7575.
