IEEE Floating-Point Operation Semantics
DuckDB follows IEEE floating-point operation semantics. If you would like to turn this off, run:  
```sql
SET ieee_floating_point_ops = false;
```  
In this case, floating point division by zero (e.g., `1.0 / 0.0`, `0.0 / 0.0` and `-1.0 / 0.0`) will all return `NULL`.
