User:Arseniiv/Factorization/Doc

This template outputs prime factorization in a pleasant form, given a plain-text expression.

For multiplication use * or simply space. For exponentiation use ** or ^. You can add extra spaces around all these, just not between - and an exponent.

One of good choices to write a readable source text is using spaces between factors and no space around exponentiation (the first two examples below).
