C++ Program to compute division upto n decimal places

Given with the value of x and y as a positive integer with the value of n for number of decimal places and the task is to generate the division up to n decimal places.

Example

Input-: x = 36, y = 7, n = 5
Output-: 5.14285
Input-: x = 22, y = 7, n = 10
Output-: 3.1428571428

Approach used in the below program is as follows −

• Input the value of a, b and n
• Check if b is 0 than division will go upto infinite and if a is 0 than result will be 0 as something divides to 0 is 0
• If n is greater than 1 than store the value of remainder and subtract it from the dividend after that multiply the result by ten. Start the next iteration
• Print the result

ALGORITHM

START
Step 1-> declare function to compute division upto n decimal places
   void compute_division(int a, int b, int n)
   check IF (b == 0)
      print Infinite
   End
   check IF(a == 0)
      print 0
   End
   check IF(n  0) && (b  0)))
      print “-”
      set a = a > 0 ? a : -a
      set b = b > 0 ? b : -b
   End
   Declare and set int dec = a / b
   Loop For int i = 0 and i  In main()
   Declare and set int a = 36, b = 7, n = 5
   Call compute_division(a, b, n)
STOP

Example

#include 
using namespace std;
void compute_division(int a, int b, int n) {
    if (b == 0) {
        cout  0) && (b  0))) {
        cout  0 ? a : -a;
        b = b > 0 ? b : -b;
    }
    int dec = a / b;
    for (int i = 0; i 
Output
5.14285
