Restaurant - Lucky Numbers Discount

       Restaurant - Lucky Numbers Discount

Every day in a restaurant two numbers X and Y are considered lucky numbers.
If the bill amount B is divisible by X, then X% discount is offered.
If the bill amount B is divisible by Y, then Y% discount is offered.
If the bill amount B is divisible by both X and Y, then no amount is to be paid.\

The program must accept X, Y and B and print the amount to be paid as the output (precision is upto 3 decimal places)

Input Format:
The first line contains B
The second line contains X
The third line contains Y

Output Format:
The first line contains the amount to be paid finally after discount.

Boundary Conditions:
1 <= X,Y <= 50
20 <= B <= 100000

Example Input/Output 1:
Input:
500
20
50

Output:
0.000

Example Input/Output 2:
Input:
100
9
10

Output:
90.000

Code:

#include <iostream>

#include<iomanip>

using namespace std;

int main(int argc, char** argv)

{

int   b,x,y;

float d;

cin>>b>>x>>y;

if(b%x==0&&b%y==0)

    cout<<"0.000";

else if(b%x==0)

    {

        d=b*(x*.01);

        cout<<fixed<<setprecision(3)<<b-d;

    }

else if(b%y==0)

{

    d=b*(y*.01);

    cout<<fixed<<setprecision(3)<<b-d;

}

else

    cout<<fixed<<setprecision(3)<<(float)b;

 }
