What will this Liquid code output?
```liquid
{% assign price = 1999 -%}
{{ price | money }}
{{ price | money_without_trailing_zeros }}
{{ price | money_without_currency }}
```
### Explanation
This question tests understanding of Shopify's money filters:
1. `price = 1999`: In Shopify, prices are stored in cents
2. `money` filter:
- Converts cents to dollars
- Adds currency symbol
- Shows two decimal places
- Output: "$19.99"
3. `money_without_trailing_zeros`:
- This is a valid Liquid filter (not null)
- Removes unnecessary zeros after decimal point
- Only removes zeros if amount has no cents
- In this case outputs "$19.99" since there are actual cents
4. `money_without_currency`:
- Shows amount without currency symbol
- Keeps decimal format
- Output: "19.99"
