The number tag wiki is this:
This challenge is intended to be solved by using, manipulating, accepting as input, or outputting numeric values.
This is pretty vague. What I'm understanding from this is the number tag should be applied any time the digits 0-9 even tenuously relate to the challenge.
- Is this a number? was tagged [number] for obvious reasons. This challenge relates to evaluating strings into numbers (mostly).
Find all the coordinates on a path was tagged [number] because the output is coordinate pairs of 2 numbers.
Generate an ascii-art non-intersecting path was tagged [number] because it takes input in the form of 2 numbers.
Coprimes up to N was tagged [number] because it requires finding a set of positive numbers that fit criteria.
All of these challenges have the tag for a different reason. Input as numbers, output as numbers, math involving numbers, and evaluating number literals.
Downside to burnination is that there are many, many (536) questions tagged number, and it might be unfeasible to replace the tag everywhere.
