No. Imagine you have this: if (x < 7) doSomething(); else doSomethingElse(); With -ffast-math, the compiler is allowed to call neither doSomething() nor doSomethingElse() if x is nan. Which IMHO is not great.

In general, recent consumer x86 CPUs will be faster at floating point code than fixed point code. Floating point multiply is already faster than integer multiply; fixed point has the additional cost of the bitshift. (which is very small, bu

Just a reminder that if 20 interested things are studied, on average you should expect 1 of them to be a false positive with p<0.05. It's a bit like throwing darts: it helps if there exists a relationship, but it also helps to be lu

Because ya'll don't have any trees. Wooden utility poles are made from a single piece of wood, usually the trunk of a pine tree. It's cheap to toss a bunch of them on the back of a truck and drive them to wherever, but they&#

To further add on to other commentators, wooden utility poles are cheap in North America and expensive in lots of places in Europe. Wooden utility poles are made of a solid trunk, not smaller pieces of wood that have been attached together.

I disagree entirely. I understand recursion just fine. I can look at a problem and think "this problem space is correctly represented by a tree/graph" and can meaningfully translate that into a program that shoves the data in

Zero is an overloaded concept. There are at least like 5 or so different things that we use the word "zero" for, some of which are very sophisticated. On the one hand, it means there's none of a thing in there. Most animals u
