I want to store a long into a character array for writing to an SD card…and then, obviously, get it back to a long! I found the below code but the long that I get back is 722 not what I put in. Since bitwise operations make my head hurt I need help badly!

```
unsigned long int longInt = 1234567890;
unsigned char byteArray[4];
// convert from an unsigned long int to a 4-byte array
byteArray[0] = (int)((longInt >> 24) & 0xFF) ;
byteArray[1] = (int)((longInt >> 16) & 0xFF) ;
byteArray[2] = (int)((longInt >> 8) & 0XFF);
byteArray[3] = (int)((longInt & 0XFF));
unsigned long int anotherLongInt;
anotherLongInt = ( (byteArray[0] << 24)
+ (byteArray[1] << 16)
+ (byteArray[2] << 8)
+ (byteArray[3] ) );
```
