I have an assignment due in my Intro to Programming class. I have it all except for one part is wrong. The program is supposed to add fractions. The problem lies with 1/11. My teacher put up his EXE file and when I compare them they are all right except my 1/11 adds to be .99999988 while his is 1.00000012. I assumed it was maybe a type conversion problem or something, but it only happens with 1/11. Can anybody offer a solution? I'm running this in Visual Basic 6.0.

#include <stdio.h>
#include <math.h>


int main ()
{

float sums[] = {0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0};
float n=0;
int m=0, q=0, x=0, y=0, z=0;

printf( "Representational Error - Sums of Fractions\n\n");

for( n=2; n<=15; ++n)
{
m = n;

for( q=1; q<=m; ++q)
{
sums[m] += (1/n);
}

if (sums[m] == 1)
{
printf( "Adding %d copies of 1/%d = %.8f, is correct.\n", m, m, sums[m]);
++y;
}
else if (sums[m] > 1.00)
{ printf( "Adding %d copies of 1/%d = %.8f, is greater than 1.00.\n", m, m, sums[m]);
++z;
}
else if (sums[m] < 1.00)
{
printf( "Adding %d copies of 1/%d = %.8f, is less than 1.00.\n", m, m, sums[m]);
++x;
}

}


printf( "\n%d sums are < 1, %d sums are = 1, and %d sums are > 1.", x,y,z);

return 0;

}

Ooble

You sure you're using Visual Basic?

Oh oops. I'm sorry. I'm using Microsoft Visual C++. But the file is a .c.

Try using the double type instead of float.
