数位位置 meaning in Chinese

bit location
bit site
digit position
digital place
digital position

The bit positions vacated by a shift are set as follows
移位操作空出的数位位置按以下方式设置：
In an arithmetic left shift , the bits shifted beyond the range of the result data type are discarded , and the bit positions vacated on the right are set to zero
在数学左移位运算中，丢弃移出结果数据类型范围的数位，而将右端空出的数位位置设置为零。
In an arithmetic right shift , the bits shifted beyond the rightmost bit position are discarded , and the leftmost bit is propagated into the bit positions vacated at the left
在算术右移位运算中，将丢弃移出最右侧数位位置的数位，并将最左侧的数位传播到左端空出的数位位置。
In an arithmetic right shift , the bits shifted beyond the rightmost bit position are discarded , and the leftmost sign bit is propagated into the bit positions vacated at the left
在数学右移位运算中，将丢弃移出最右侧数位位置的数位，并将最左侧的（符号）数位传播到左端空出的数位位置。
