creating even numbers
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.
