描述

The argument-handling of min, max, and minmax is currently somewhat inconsistent:

  • min and max can have 1+ arguments (code for 3+ args here), but minmax can only have 1 or 2 arguments (from discourse)
  • all three can have 1 numeric argument, but this is not mentioned in the docstrings
  • min and max support missing (returning missing), but throw a MethodError with a single missing argument ala min(missing)
  • minmax(missing, 1) is incorrect, returning (1, missing) rather than (missing, missing) — this is a clear bug

These are all easy to fix, so marking as "good first issue". Feel free to submit a single PR for just one of the above items.

研究方向
The issue identifies inconsistencies in base/operators.jl for min, max, minmax. The first item requires extending minmax to accept varargs. The second involves updating docstrings. The third and fourth are bug fixes for missing handling. Each can be done independently; a single PR for one item is acceptable.
