查询词典 decimal arithmetic

Right shifting an unsigned quantity always fits the vacated bits with zero. Right shifting a signed quantity will fill with bit signs ("arithmetic shift") on some machines and with 0-bits ("logical shift") on others.

在对unsigned类型的无符号值进行右移位时，左边空出的部分将用0填补；当对signed类型的带符号值进行右移时，某些机器将对左边空出的部分用符号位填补，而另一些机器则对左边空出的部分用0填补。
