hex to decimal question

Tags: decimal, hex, complement
Hi,

I have a question reguarding conversion from hex number to a decimal.

I have one  bytes of information represented in hex(these bytes were inputed from a usb games controller)
 
BYTE B: 0xFFFFFFF2
 
When I convert it to decimal it prints out -14.
It should convert it to 242.

The only way I can do this is to take away the 7 F's from the start and just convert F2 to Dec. I think it has something to do with 2's complement representation being -14. If so how do I get my code not to take 2's complement into account....

Would appreciate any help regarding 2's complement and hex conversion...

Thanks
