Conversion of Hex to Two's Compliment

example.js

// Conversion to Two's Complement

//Note that this works both ways. If you have -30, and want to represent it in 2's complement, 

// take the binary representation of 30:

0000 0000 0000 0000 0000 0000 0001 1110

// Invert the digits.

1111 1111 1111 1111 1111 1111 1110 0001

// And add one.

1111 1111 1111 1111 1111 1111 1110 0010

// Converted back into hex, this is 0xFFFFFFE2. 

// And indeed, suppose you have this code:

```

#include <stdio.h>

int main() {
    int myInt;
    myInt = 0xFFFFFFE2;
    printf("%d\n",myInt);

    return 0;
}

```

// That should yield an output of -30. Try it out if you like.
