comment Does the commutative property not apply when multiplying Quaternions
@fleablood Thanks, now that I think about it quaternion multiplication is matrix multiplication. Since quaternions are points on a cartesian 4D hyper-field, they can be represented as vectors on [r, i, j, k]. e.g. "j" could be seen as [0,0,1,0]

@user26857 There was a downvote, it has since then been removed. I'm not sure why it's pathetic, I simply wanted to know what I had done wrong so that I could avoid getting more downvotes in the future? I'm sorry that I've offended you sir

Thank you! That's fascinating. I'd like to understand why this is the case, in an intuitive sense.

@T.Bongers So even in the article you linked it says jk=i, kj=-i :o Is this really the case? jk≠kj ?

Now that I understand more intuitively what logarithms actually are I redact my above comment. This is still a nice solution though :D

Just curious, is the use of rounding brackets [ ] intentional? Or did you mean to use parens ( ) -- en.wikipedia.org/wiki/Nearest_integer_function
