sign value

基本解釋

isSigned() to determine if a parameter can hold signed numerical values.
isSigned()，用于確定參數(shù)是否可以保存有符號(hào)的數(shù)值。
According to K&R Second edition (the bible) the results are implementation-defined for right-shifts of signed values.
根據(jù) K&安培； R第二版（圣經(jīng)）結(jié)果是實(shí)現(xiàn)定義的符號(hào)值的右移。
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號(hào)的數(shù)值范圍內(nèi)的較小值，如果范圍內(nèi)既包括正值和負(fù)值，那最小值就默認(rèn)為零。
