## Operators are functions
## Operators are functions
For templates, the operators (`eq`, `ne`, `lt`, `gt`, `and`, `or` and so on) are all implemented as functions. In pipelines, operations can be grouped with parentheses (`(`, and `)`).
Operators are implemented as functions that return a boolean value. To use `eq`, `ne`, `lt`, `gt`, `and`, `or`, `not` etcetera place the operator at the front of the statement followed by its parameters just as you would a function. To chain multiple operations together, separate individual functions by surrounding them with paranthesis.
```yaml
{{/* include the body of this if statement when the variable .Values.fooString exists and is set to "foo" */}}
{{ if and .Values.fooString (eq .Values.fooString "foo") }}
{{ ... }}
{{ end }}
{{/* do not include the body of this if statement because unset variables evaluate to false and .Values.setVariable was negated with the not function. */}}
