操作符

Kotlin支持标准的数学操作，下面罗列了按位的相关操作函数：

• shl(bits) – signed shift left (Java's << )

• shr(bits) – signed shift right (Java's >> )

• ushr(bits) – unsigned shift right (Java's >>> )

• and(bits) – bitwise and

• or(bits) – bitwise or

• xor(bits) – bitwise xor

• inv() – bitwise inversion(转向)

    val x = (1 shl 2)
    val y = (8 shr 2)
    val z = (0xFFFF ushr 31)
    val a = 1 and 2
    val b = 1 or 2
    val c = 1 xor 2
    val d: Int = 11
    val e: Int = d.inv()
