Hi

 CC Gain Data Type  IS  F4，I Get the raw data from the dataflash,But I use the IEEE754 float after format conversion, And it shows that the values are not equal, how do I convert? for example,I get raw data is 0x91,0x71,0x20,0x00,it display is 123456, but use IEEE754  float format conversion is 0x47, 0xf1, 0x20, 0x00, why the two are not equal, How should I do?

Thanks
