Wow, that's a lot of work you put into it. I really appreciate it! However, I fail to use it. 1. ~~Why is ci32 a vector and not just a...

I love your commitment, that you have put into it! A drawback of using your proposed ASM is, however, that it is not platform agnostic. I have found, that at...

Thank you for detailed insights! > Perhaps I should define these type aliases myself? What would be the best name? V[scalar type]? Sounds like a good option.

If the offending line is [here](https://github.com/PainterQubits/Unitful.jl/blob/7ff5c0d7cbdce4500c6f96d28b7b8eec061380f9/src/conversion.jl#L106). Why does the performance regression only occure in the case of `@fastmath`?

Even for 2-argument it gets slower: ```julia test!(y, z, H, x) = y .= z .- Mul(H, x) function test1!(y, z, H, x) mul!(y, H, x) y .= z .-...

Indeed: ```julia test2!(y, z, H, x) = y .= (-1.0) .* Mul(H, x) .+ z @benchmark test2!($y, $z, $H, $x) BenchmarkTools.Trial: memory estimate: 0 bytes allocs estimate: 0 -------------- minimum...

I think the most common one is the mathematically one. Wolfram Alpha is also using the mathematical definition: http://mathworld.wolfram.com/SphericalCoordinates.html And it is the same for mathinsight.org: http://mathinsight.org/spherical_coordinates Unfortunately I can't...

I have got the same error in v1.6: https://github.com/JuliaGNSS/GNSSReceiver.jl/runs/8154848031?check_suite_focus=true#step:18:52 The error does not appear in v1.8 though.

+1 It currently results into this error: ``` KeyError('bottom',) File "/usr/lib/python3.5/site-packages/matplotlib2tikz/save.py", line 134, in save data, content = _recurse(data, figure) File "/usr/lib/python3.5/site-packages/matplotlib2tikz/save.py", line 218, in _recurse ax = axes.Axes(data, child)...
