You may call fread first to get 4 bytes and then swap them in little endian format. This method is a little bit tricky to use since the float primitive can handle more precision than byte value thus if we will use the this method we might lost the precision the original value has. Only the first 1,500 bytes are considered by queries. This method has two overloaded variants too where you can pass the charset to be used for encoding. Text.
