Subject: Re: [algogeeks] Help on modular arithmetic
Hi Faran,
Let's say b/a=q, b%a=r; The cond. to be satisfied is b=a*q+r; When dealing with -ve numbers there may be more than one way to satisfy this cond. So, the c language follows the foll. rule :- sign(q)= sign(a)*sign(b); and sign(r)=sign(b);
So, you need 2 find such q and r with above signs & satisfying above condition. And such a 'r' wud be ur required answer.
==>
-22%3 = -1; (sign of numerator)
-22%-3 = -1; (sign of numerator)
Cheers,
siva.

Can you guys tell me what will the answers of following operations:
1. -22 % 3 = ?
2. 22 % -3 = ? (This one I know actually, it will be 2, I know the
calculation but do not know the explanation)
3. -22 % -3 = ?
Thanks in advance.
