Kotlin 数据类型

Posted 2020-10-08 ARM830

Kotlin 的常见数据类型：

类型	范围
byte	-128~127
short	32767 -32768
int	-2147483648~2147483647
long	9223372036854775807 -9223372036854775808
float	小数点6位
double	小数点后16
string	无

 验证代码：

fun main(agrs : Array<String>)
{

var B:Byte= Byte.MAX_VALUE;
    println("max:"+B);
   B= Byte.MIN_VALUE
    println("min:"+B);

    var nub:Int=Int.MAX_VALUE;
      println("Max:"+nub)
    nub=Int.MIN_VALUE
    println("Min:"+nub)

    var nub_short:Short=Short.MAX_VALUE;
     println("Max:"+nub_short)
    nub_short=Short.MIN_VALUE
     println("Min:"+nub_short)

    var nub_long:Long=Long.MAX_VALUE;
    println("Max:"+nub_long)
    nub_long=Long.MIN_VALUE
    println("Min:"+nub_long)

    var nub_double:Double=Double.MAX_VALUE
    println("Max:"+nub_double)
    nub_double=Double.MIN_VALUE;
    println("Min:"+nub_double)

}
