Separate an integer into two (nearly) equal parts

Question

I need to separate an integer into two numbers. Something like dividing by two but I only want integer components as a result, such as:

6 = 3 and 3
7 = 4 and         


        

Answer 1

Just find the first part and subtract it from the original number.

var x = 7;

var p1 = Math.floor(x / 2);
var p2 = x - p1;

console.log(p1, p2);

In the case of x being odd, p1 will receive the smaller of the two addends. You can switch this around by calling Math.ceil instead.
