  creating even numbers

  Posted by Kevin Camp on October 11, 2007 at 8:16 pm

  is there a better way to restrict values to even numbers than this:

  Math.round((value / 2) + 0.49) * 2;

  i’m dividing a value by 2 adding a fraction, rounding that and then multiplying the result by 2… it just seems like there should be an easier way…

  Not much simpler:

  Math.round(value/2)*2

  Or, if you don’t want it to change to 2 until it value gets to 2:

  Math.floor(value/2)*2

  thanks dan,

  i just figured out how i might manipulate the % function (what’s % called anyway.. remainder?):

  value + (value%2)

  % is called the modulus operator.
