将表达式的位左移，然后将结果赋给第一个参数。
Shifts the bits of an expression to the left, and assigns the result to the first argument.
我们可以在序列化之前模糊化该数据，将数位循环左移一位，然后在反序列化之后复位。
We can obscure this data by rotating the bits once to the left before serialization, and then rotate them back after deserialization.
因此，只需将内容向左移位四个字节到新的寄存器来获得在首选槽内的低阶位。
Therefore, you just shift the contents to the left by four bytes into a new register to get the low-order bits in the preferred slot.
在内部，可以用任意精度任何范围的值和一个换算因子来表示BigDecimal，换算因子表示左移小数点多少位，从而得到所期望范围内的值。
Internally, BigDecimal is represented as an arbitrary-precision unscaled value and a scale factor, which represents how many places to move the decimal point left to obtain the scaled value.
利用传输门实现了32位桶式移位寄存器，其具体功能包括算术右移，逻辑左移，逻辑右移和循环右移。
In this paper, we realized Barrel Shifter of 32 bits by using transpost gates, its functions including arithmetic shift right, logic shift left, logic shift right and rotate right.
在这种情况下，会将32位值左移，其结果是值强制转换为64位值。
In this case, a 32-bit value was shifted left, and the result of that shift was cast to a 64-bit value.
在这种情况下，会将32位值左移，其结果是值强制转换为64位值。
In this case, a 32-bit value was shifted left, and the result of that shift was cast to a 64-bit value.
