Detect if number is odd or even. - Redirect Left - 27.03.2009

Hello!

How can I tell if a number is odd, or even?

Quote:

e1 % e2
Results in the remainder of the division of e1 by e2. The sign
of the remainder follows the sign of e2. Integer division and
remainder have the Euclidean property: D = q*d + r, where
q = D/d and r = D%d.

You would have to divide the number by 2 and if there is no remainder...its even. If there is a remainder...its odd.

I >>sUCK<< at math tho..so doulbe check that.

Code:

IsNumberEven(number) {
  new remainder = number % 2;
  if(remainder > 0) return false;
  else return true;
}

^try that, maybe?

Test:

pawn Code:

#define IsOdd(%0) %0 % 2

then, !IsOdd = IsEven
