# Built-in Functions
|
|
|
|
The HCL language includes a number of built-in functions that you can
|
|
call from within expressions to transform and combine values. The general
|
|
syntax for function calls is a function name followed by comma-separated
|
|
arguments in parentheses:
|
|
|
|
```hcl
|
|
max(5, 12, 9)
|
|
```
|
|
|
|
For more details on syntax, see
|
|
[_Function Calls_](./expressions.html#function-calls)
|
|
on the Expressions page.
|
|
|
|
The HCL language does not support user-defined functions, and so only
|
|
the functions built in to the language are available for use. The navigation
|
|
for this section includes a list of all of the available built-in functions.
