FAQ
The value is repeatedly divided by sixteen and remainders 10 through 15 become the letters a through f, so 255 converts to ff.
Output uses lowercase digits such as ff. Hexadecimal is case-insensitive, so you can uppercase it after copying if your style guide requires it.
Common cases include building CSS color channels, reading memory addresses, setting register values, and encoding byte offsets in file formats.
