C# Modbus协议中读取浮点数的操作方法

输入参数P1,P2代表PLC中浮点数储存的两个寄存器获取的数据

public static float GetFloat(ushort P1, ushort P2)
        {
            int intSign, intSignRest, intExponent, intExponentRest;
            float faResult, faDigit;
            intSign = P1 / ;
            intSignRest = P1 % ;
            intExponent = intSignRest / ;
            intExponentRest = intSignRest % ;
            faDigit = ( + P2) / ;
            faResult = (, intSign) * (, intExponent - ) * (faDigit + );
            return faResult;
        }
