MINIMUM refers to the smaller magnitude limit of a range of like-signed VALUEs; if the range includes both positive and negative VALUEs, the MINIMUM is implicitly zero.

最小值是指限制在一些有符号的数值范围内的较小值，如果范围内既包括正值和负值，那最小值就默认为零。

Treating numerical values as text yields incorrect results, especially if those values are signed; therefore, the column text must be converted to a numerical type.

将数字作为文本对待会产生错误结果，尤其是当这些值是有符号数字时，因此，列文本必须转换为数字类型。

Given the same number of bits, unsigned integers usually represent twice the number of absolute values representable by signed integers.

给予相同的位元，无号整数通常能表示由有号整数所代表的值的绝对值的两倍数目。
