# asin(n)

Returns the arcsine value of radians value _n_. _n_ can be any real numeric value in the range of -1 \<= _n_ \<= 1. If `null` is passed as an argument, `asin()` returns `null`.This function can only be used in a `foreach` statement.

## Example

```nolang
q = foreach q generate asin(radians) as arcsine;
```
