What is the fastest integer division supporting division by zero no matter what the result is?
...fore took philipp's first code and my code and ran it through the compiler from ARM and the GCC compiler for the ARM architecture, which features predicated execution. Both compilers avoid the branch in both samples of code:
Philipp's version with the ARM compiler:

Strongly typed means, a will not be automatically converted from one type to another. Weakly typed is the opposite: Perl can use a string like "123" in a numeric context, by automatically converting it into the int 123. A strongly typed language like python will not do this.
Statical...
Can I list-initialize a vector of move-only type?
...r idea... What if we don't create a temporary array and then move elements from there into the vector, but use placement new to initialize this array already in place of the vector's memory block?
Here's my function to initialize a vector of unique_ptr's using an argument pack:

One catch from your quote of the standard. The "except where noted", IIRC, includes an exception when dealing with an overloaded operator, which treats the operator as a function and therefore creates a sequence point between the first...

In order to keep the aspect ratio of the div and prevent its content from stretching it, you need to add an absolutely positioned child and stretch it to the edges of the wrapper with:
div.stretchy-wrapper {
position: relative;
}
div.stretchy-wrapper > div {
position: absolute;
