OJ Board

Here is the status of my code now. With all the corrections suggested. But still get WA.

[c]#include <stdio.h>
#include <math.h>
#define MAX 100

int main()
{
double a[MAX][MAX],b[MAX][MAX],c[MAX][MAX];
double d,m;
int i,j,k,p,n=0;

while(scanf("%d",&n))
{
if(n==0) return(1);
p=1;
for(i=0;i ...

Ok, I've changed that.
But what's the matter then?

I've read on another thread that that case should be not possible.
I've tried with that case answering 0.200000, but still get WA.

Ok, i've tried with the epsilon and I still got WA. If I change the type from float to double, fails all. Even the sample tests are correct.

Here my sample inputs:
2
1 2
2 1

2
1 2
2 1

4
1 0 0 0
0 1 0 0
0 0 0 1
0 0 1 0

10
9.5013 6.1543 0.5789 0.1527 8.3812 1.9343 4.9655 7.2711 7.9482 1.3652
2 ...

what is an epsilon?

I've tried my code with all test inputs and outputs found in this board, but i still get WA.
What happens to this code? How can I get AC?

[c]#include <stdio.h>

# define MAX 100

int main()
{
float a[MAX][MAX],b[MAX][MAX],c[MAX][MAX];
float d,m;
int i,j,k,p,n=0;
