byte conversion chart

Recently, the Modbus protocol requires the conversion of floating point numbers. Originally, we wanted to follow the IEEE floating point structure. Google had a better solution, and pasted it for future use.Code(The code is just for illustration and you can organize it yourself ): 1. Convert the byte array to single and input parameters for processing. Function bytestosingle (): single; 2. Convert si

Label:The basic idea of converting a horizontal table to a vertical table is: 　　1) The horizontal table of multiple data, "pressure" into one. The equivalent of grouping so many, each group "presses" into one piece of data. Using GROUP BY 2) The columns in the vertical table are populated with the data for a particular row, using the value end that is not used in case of ' a ' then ' B ' else, in order to filter some unused data, the commonly used function has Max (), SUM () PS: If there is no a
