Thread: java -working with decimal numbers

hello java forum,
Good Morning.


Here i came up with a mess about a program.

Iam not obtaining a accurate result .

But , in C the program is giving an accurate result.



in java , the program goes like this

public class FloatingNumber {
public static void main(String...args) {
double i;
double num=0.0;
for(i=0.0;i<10;i++)
num=num+0.1;
System.out.println(num);
}
}

// output =0.9999999999999999

// In C the program goes like this

#include<stdio.h>
#include<math.h>
main()
{
double i, num=0.0;
for(i=0;i<10;i++)
num=num+0.1;
printf("%f",num);
}

// output =1.00000

please explain me the difference and resolve my problem.

Thanks in advance
