represent non-negative values. This is because the highest-order bit is reserved for the sign in a signed integer, while it can be used for additional positive values in an unsigned integer. The specific range of values that can be represented by each type depends on the number of bits ...

在任何可能的情况下,使用numeric类型进行计算会得出准确的结果,例如加,减,乘。但是,与integer类型或下一节中...,没有任何额外的前导或尾随零。因此,声明的列的精度和小数位数是最大值,而不是固定分配。(从这种意义上讲,numeric类型更类似于varchar(n)而不是char(n)。)实际的存储需求是每组四个...
Beginning with C# 11, you can use list patterns to match elements of a list or array. The following code checks arrays for integer values in expected positions: C# Copy int[] empty = []; int[] one = [1]; int[] odd = [1, 3, 5]; int[] even = [2, 4, 6]; int[] fib ...
