Question

What is the output of this code?
var a = 66;
var b = a % 4;
var c = b % a;
alert(c); answer 2

Answer 1

The "%" operator represents modulus division. It gives the reminder after the division. First operation b = 66 % 4 = 2 (because 16*4= 64 => reminder is 2). Second operation c = 2 % 66 (here the reminder is 2, because 2 < 66).

Answer 2

You should get whole number after the division and check the reminder. So in this case it is not possible and 2 is the reminder.

Answer 3

Another try to explain it 2 % 66 => 1 times 66 is 66 > 2, so it's not possible, 0 times 66 is 0 and the reminder is 2 - 0 = 2.

Answer 4

что именно ты хочешь вывести

Answer 5

2/66=0,030303030303

Answer 6

почему вторая операция деление по модулю 2%66 равно на 2 ?

Answer 7

whenever you do x%y, output will be x if you have y>x == true
