Hi there,

it looks like some operators are missing, like:

- `//`: integer division
- `~`:bitwise XOR
- `&`, `|` (bitwise AND and OR)

Is there any way (or plan) to add them?

Thank you

Welcome to the forum.

Processing supports multiple languages so to answer your question we need to know which mode /language you are interested in.
