actionscript数字介于():Boolean之间

Actionscript是否具有接受数字的内置函数,如果此数字介于2个数字之间,则可以返回布尔值.

例如

3 is between 2 and 6   //returns true
5 is between 10 and 20 //returns false

不,但你可以自己轻松编写代码:

public static function isBetween(x : Number, low: Number, high : Number) : Boolean {
    return ((x>=low)&&(x<=high));
}

因此,对于您的示例,isBetween(3,2,6)返回true,而isBetween(5,10,20)返回false.也就是说,简单地使用布尔表达式((x> = 2)&&(x <= 6))比isBetween(x,2,6)更具可读性.
