Math {#language.math}
====

Math can be applied directly to variable values.


    {$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`"}
