无符号右移,忽略符号位,空位都以0补齐 value >>> num -- num 指定要移位值value 移动的位数。 无符号右移的规则只记住一点:忽略了符号位扩展,0补最高位 无符号右移运算符>>> 只是对32位和64位的值有意义 E | hongtenzone@foxmail.com B |http://www.cnblogs.com/hongten...
The bitwiseshift operators shifts the bit value. Theleft operand specifies the value to be shiftedand theright operand specifies the number of positions 位移位运算符对位值进行移位。左操作数指定要移位的值,右操作数指定值中要移位的位的数目
shift operators (用到的机会比较少,暂时不深入学习) The shift operators also manipulate bits. They can be used solely with primitvie, integral type(注意:不只是integer类型). The left-shift operator (<<) The signed right-shift operator (>>) ...
If the promoted type of the left-hand operand is int, only the five lowest-order bits of the right-hand operand are used as the shift distance. It is as if the right-hand operand were subjected to a bitwise logical AND operator & (§15.22.1) with the mask value 0x1f (0b11111). ...
and the signed right shift operator ">>" shifts a bit pattern to the right. The bit pattern is given by the left-hand operand, and the number of positions to shift by the right-hand operand. The unsigned right shift operator ">>>" shifts a zero into the leftmost position, while the...
