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

Another way to do this is using bitwise operators. It doesn't work for very big numbers

function splitter(number){
  part1 = (number>>1) + (number&1);
  part2 = number>>1;
  console.log(number + ":", part1 + "+" + part2);
}

splitter(7);
splitter(6);
splitter(2**30+1); // Breaks for values greater than 2**31
splitter(2**31+1);
