The allowed number representations are two ' s - complement , one ' s - complement , and signed - magnitude . note that all of these number systems agree on the representation of positive numbers.
允许的数字表示法是二补数,一补数,和符号量值。注意所有这些数字系统同意正数数字的表示。
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。
