Is this just for display purposes (using it in a message), or do you want
to store the value like that? You can use `printf` in a template for
changing the precision, for example:
```
|alert()
.message('Percentage value is {{ index .Fields "value" | printf "%0.2f"
}}%')
```
I'm not sure if there's a way to store the value that way, though.
