hexfriendly

Hexfriendly refers to a system or convention where hexadecimal numbers are represented in a way that is easy for humans to read and work with, often by avoiding certain problematic characters or by using specific formatting. In computing, hexadecimal (base-16) is frequently used for memory addresses, color codes, and data representation. However, the standard hexadecimal digits (0-9 and A-F) can sometimes be confused with uppercase or lowercase letters, or are difficult to distinguish from other characters when typed quickly.

A hexfriendly approach might involve using a consistent case for hexadecimal digits, such as always using lowercase or always using uppercase. Another aspect could be the use of prefixes or suffixes to clearly indicate that a number is hexadecimal, like `0x` for C-style languages or `h` at the end. Some systems might choose to avoid hexadecimal digits that resemble other characters, though this is less common. The primary goal is to reduce ambiguity and improve the accuracy of human input and interpretation of hexadecimal data. This can be particularly important in environments where manual entry or transcription of hexadecimal values is common.
