# Math
|
||
|
|
|
||
|
|
Math can be applied directly to variable values.
|
||
|
|
|
||
|
|
## Examples
|
||
|
|
```smarty
|
||
|
|
{$foo+1}
|
||
|
|
|
||
|
|
{$foo*$bar}
|
||
|
|
|
||
|
|
{* some more complicated examples *}
|
||
|
|
|
||
|
|
{$foo->bar-$bar[1]*$baz->foo->bar()-3*7}
|
||
|
|
|
||
|
|
{if ($foo+$bar.test%$baz*134232+10+$b+10)}
|
||
|
|
|
||
|
|
{$foo|truncate:"`$fooTruncCount/$barTruncFactor-1`"}
|
||
|
|
|
||
|
|
{assign var="foo" value="`$foo+$bar`"}
|
||
|
|
```
|
||
|
|
|
||
|
