Very interesting, you are right. The IEEE 754 standard defines positive/negative zero as not subnormal numbers. Mechanically speaking, the two zeros use the subnormal number format, so in that sense they are subnormal (but definitional

I think the notion of fractional pixels is rare indeed. But I can think of one example from astrophotography. After taking a photo, we use software to analyze the size of stars - for features like autofocus, auto-guiding, and detecting smea

I can think of one useful property of subnormal numbers off the top of my head. If subnormal processing is enabled, then for all finite values of `a` and `b`, `a != b` if and only if `a - b != 0`. But if subnormals are flushed to zero, then

In certain personal projects, I have the opposite philosophy where I don't want quality. I got addicted to designing models and 3D-printing them a year ago. Over time, I learned to reduce the amount of safety factor and make items just

I didn't learn much from reading this article. Questions linger in my mind, for example: What are the CIE XYZ coordinates of each colored square? What is the spectral distribution of each square? How were the colors chosen?

Kudos to the author for explaining these concepts, but I personally find this to be a poor use of my time and mental capacity. I dabbled in C++ programming before Rust 1.0 was released (year 2015). I have spent some time understanding thing

In this port, using the menu to disable the music has no effect. Surprisingly, typing "hidden test" does have an effect, but the interpretation of mouse movements is weird and uncontrollable, unlike the original Windows EXE game.
