Question

I am a C++ newbie and having a problem with my first program. I’m trying to multiply two float numbers and the result always show like 1.1111e+1 where 1s are the random numbers. Following is the little program I wrote.

#include <iostream>
#include <string>
#include <conio.h>
using namespace std;
int main()
{
  float bank;
  float dollor;
  cout<<"Enter amount of $ deposited at Bank: ";//the data to input is 5000
  cin>>bank;
  cout<<"Enter current $ price: ";//1usd = 800mmk: the data to input is 800
  cin>>dollor;
  bank*=dollor;//all deposited $ to local currency
  cout<<"Result is "<<bank;
  getch();
}

and the result of this program is 4e+006.

ps: I declared as float in order to input floats sometime.
Please help me with this program where I was wrong. Thanks all..

Answer 1

4e+006 is the scientific notation for 4000000, which is the correct answer to 5000*800.

To elaborate, 4e+006 stands for 4 * 10**6, where 10**6 is ten to the sixth power.

To use the fixed-point notation, you could change your program like so:

#include <iomanip>
...
cout << "Result is " << fixed << bank;
