통신편정수거류형십진제부점수
为智能仪表提供一种"十进制浮点数",其特点是值域宽、值准确,它能代替整型、长整型、三字节浮点数、四字节浮点数、BCD码数。用它通信可简化和统一仪表的通信协议,为制定仪表通用通信协议标准创造条件。

A decimal floating point data type is stated for intelligent instruents. Its features include wide value domain and high precision. It can replace integral, long integral, three-byte floating point data, four-byte floating data and BCD code data. The communication can be simplified and the protocol can be uniformed by using this data type. Thus it creates the basis for drawing up the generic commication protocol.
