This is a way to format strings, such as decimal numbers and such. Use
the syntax for [`sprintf()`](https://www.php.net/sprintf) for the
formatting.

{$myVar|string_format:"%d"}
```

|--------------------|--------|----------|---------------------------------------|

## Examples

```php
<?php

$smarty->assign('number', 23.5787446);

```

Where template is:

```smarty
{$number}
{$number|string_format:"%.2f"}
{$number|string_format:"%d"}
```

Will output:

```
