rel_exp - Comparison Type of Elementary Data Objects
The following sections describe which comparison types are produced by combining different elementary data objects. They also include the rules that determine the length in which the comparison is made when comparison types have generic lengths.
Other versions: 7.31 | 7.40 | 7.54
