Subject: Arithmetic Zero
Date: Tue, 5 Mar 2024 06:28:04 +0300	[thread overview]
Message-ID: <47117922-e17f-44d1-8a2f-2cb4a9c53606@outerface.net> (raw)


I believe -e is best practices for scripts, so have:

```
#!/bin/zsh -e
(( test = 0 ))
echo $test
```

and it doesn't work of course.

1. What is the reason for returning 1 when an arithmetic evaluation 
succeeds but is zero?

2. How to do arithmetic evaluation properly in zsh sripts? postpend with 
  || true
