Hey all!

I have little experience using Haskell outside of Tidal, so this question might be a bit silly.

I'm trying to sample from an exponential probability distribution using its quantile function:

```
rexp :: Pattern Double -> Pattern Double
rexp lambda = log (1 - p) / lambda * (-1) where
p = rand
```

`p`

must be a random number between 0 and 1, hence `p = rand`

.

However, if I run

```
d1 $ slow (rexp 1) $ s "bd"
```

I get the error `Couldn't match type 'Double' with 'Ratio Integer'`

. I have tried changing the input-output types, but still ran into issues.

How can I solve this? Is there a better way to achieve what I want?
