negative numbers

[Hung Tang]

How do you write a negative number in binary form? Say -1 is 11111111 but how?? What would be -125 in binary? And can anyone determine what 5>>38023 would be?
Thanks

Here is a good post dealing with that:

Short answer, do a search for bit operations in the forum - you'll find a ton.
Slightly longer answer, when shifting by a value greater than the number of bits in the value you're shifting, take that value and mod it by the size of the value you're shifting.
For example:

5 >> 38023 = 5 >> 38023 % 32 (an int is 32 bits in Java) = 5 >> 7.
