# sign(n)

Returns 1 if the numeric value, _n_ is positive. It returns -1 if the _n_ is negative, and 0 if _n_ is 0. _n_ can be any real numeric value in the range of -1e308 \<= _n_ \<= 1e308. If `null` is passed as an argument, `sign()` returns `null`. This function can only be used in a `foreach` statement.

## Example

```nolang
q = foreach q generate sign(value) as value;
```
