Radoria Posted December 12, 2014 Share Posted December 12, 2014 Not really a bug as much as a design feature. Can save memory by using a smaller container. The HUD exp is stored as a 16 bit integer. It'll reset every 216 or 65,535. If they would have used a 32 bit integer instead, it would reset at 232 or 4,294,967,295. Quote Link to comment Share on other sites More sharing options...

The mystery to me is why it shows negative numbers for a while after it overflows the 64k. 2s-complement won't explain it, else they would need 4 bytes to express the 64k. I suspect that whatever operator they used to increment the number uses an intermediate variable of more than 2 bytes which it perhaps then reduces to 2 bytes BCD for display. The overflow bit is taken to be a negative sign. 1 Quote Link to comment Share on other sites More sharing options...
