除 is [not] even是否为偶数 is [not] even by $b即($a / $b) % 2 == 0 is [not] odd是否为奇 is not odd by $b即($a / $b) % 2 != 0 ⽰例：

equal/ not equal/ greater than/ less than/ less than or equal/ great than or equal/后⾯的就不⽤说了

Smarty 中的 if 语句和中的 if 语句⼀样灵活易⽤，并增加了⼏个特性以适宜模板引擎. if 必须于 /if 成对出现. 可以使⽤ else 和 elseif ⼦句. 可以使⽤以下条件修饰词：eq、ne、neq、gt、lt、lte、le、gte、ge、is even、is odd、is not even、is not odd、not、mod、div by、even by、odd by、==、!=、>、<、<=、>=. 使⽤这些修饰词时必须和变量或常量⽤空格格开.
