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

var number = 7;
var part1 = 0;
var part2 = 0;

if(number == 0) {
    part1 = (part2 = 0);
    console.log(part1, part2);
}
else if(number == 1) {
    part1 = 1;
    part2 = 0;
    console.log(part1, part2);
}
else if((number % 2) == 0) {
    part1 = part2 = number / 2;
    console.log(part1, part2);
}
else {
    part1 = (number + 1) / 2;
    part2 = number - part1;
    console.log(part1, part2);
}

Only other solution, I think performance is OK.
