Data types ending in "ish" mean that either the data type or a value that can be converted to the type are accepted. For example "numberish" means either a number or something else that is then converted to a number, say a text value or "1.5".

Note that all data types are "textish" because they can always be rendered as text. Whether that value is meaningful or not is another matter!

abs ⛔

Returns the absolute value of a numberish value provided on its input. If the input is not numberish then an error is reported.

Example (from the Liquid docs):

{{ -17 | abs }}
{{ 4 | abs }}

append ⛔

Appends the text given as a parameter to the input and returns the result.
