In Python this is a handy operation on arrays:

[https://docs.scipy.org/doc/numpy/reference/generated/numpy.clip.html](https://docs.scipy.org/doc/numpy/reference/generated/numpy.clip.html)

Is there a function in Julia for achieving the same result? If not, can I open an issue on GitHub with a feature request?

Perhaps this is what you are looking for

```julia
help?> clamp
search: clamp clamp!

  clamp(x, lo, hi)

  Return x if lo <= x <= hi. If x < lo, return lo. If x > hi, return hi.
  Arguments are promoted to a common type. Operates elementwise over x if x is
  an array.

```

Perfect, I still don’t understand how can I mark questions as solved on Discourse, sometimes I have the option, sometimes I don’t. Do I need to tag the thread with `question`?

Well, I didn’t mark anything so I thought you did. Maybe someone with mod power did. I’m not sure how to mark as solution, I thought there was a button under each post you could click.

Sorry, I think it was @ihnorton that marked it? I got a notification in the upper right saying that my post was edited by him. Only admin can mark as solved?

I created a new topic for this question, it turns out it is important:

> [@How to mark a question as solved?](https://discourse.julialang.org/t/how-to-mark-a-question-as-solved/1703):
>
> Sometimes I see the checkbox below the answers, sometimes I don’t. Can you elaborate on how discourse decides on that?
