If I understand correctly, there is no gain when applying this patch to
Generator. I'm not that surprised that this is the case since the compiler
is much more limited in when it can do in Generator than what it can when
filling a large array directly with functions available for inlining and
unro
This is very comforting news :) Welcome back

My reading is that the first 4 are pure C, presumably using the standard practice of inclining so as to make the tightest loop possible, and to allow the compiler to make other optimizations. The final line is what happens when you replace the existing ziggurat in NumPy with the new one. I read it

That is good news indeed. Seems like a good upgrade, especially given the breadth of application of normals and the multiple appearances within distributions.c (e.g., Cauchy). Is there a deprecation for a change like this? Or is it just a note and new random numbers in the next major? I think thi
