Division without operator

Problem Statement:
      Find the quotient without using the operator ('/').

Solution:
Run Source Code

Below is the implementation:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36

/** * Division without using '/' operator * @author PRATEEK */ public class Division { public static int division(int dividend, int divisor) { if (divisor == 0) throw new ArithmeticException("Division by Zero"); boolean isPositive = true; // flag for negative number if (dividend < 0) { isPositive = !isPositive; // toggle flag, i.e.negative dividend *= -1; // make divident positive } if (divisor < 0) { isPositive = !isPositive; divisor *= -1; } int temp, mul, result = 0; for (; dividend >= divisor; dividend -= temp >> 1, result += mul >> 1) for (mul = 1, temp = divisor; temp <= dividend; temp <<= 1, mul <<= 1); return result; } public static void main(String[] args) { int numerator = 56; int denominator = 5; int ans = division(numerator, denominator); System.out.println(numerator+"/"+denominator+"="+ans); } }
