Data Division returning a negative number

Hi All,

Just faced an interesting thing in HP-UX. I was dividing 2955334616 / 2 by using echo `expr 2955334616 / 2` , and this ofcourse which expects 1477667308 to be returned. But I am getting -669816340 and I am Smilie how exactly this is possible. It is not one of the compliments (Ones or Twos) and not an understandable phenomea.

Can somebody please clarify this interesting phenomena.

32-bit signed "integer" boundary (2147483647). Try echoing the equation into "bc"

Hi Citaylor,

Thanks for the immediate response. But it seems that the same result is being returned.

# echo `expr 2955334616 / 2`
# echo `expr 2955334616 / 2` | bc
# (echo `expr 2955334616 / 2` ) | bc

Anym more thoughts?

echo "2955334616/2" | bc
