#### Darius Fatakia

i'm new to MS Visual Studio and C++ but not to C programming in general. i'm

trying to divide two integers and get their actual quotient (eg 5/3 =

1.666667 etc). i thought i had type cast correctly, but please let me know,

because it appears to be rounding off. my code follows. Thanks!

void DrawLine(GLint x1, GLint y1, GLint x2, GLint y2)

{

int i, pk, dy, dx, yc, xc, inc, temp;

float m;

/*

x1 = 100;

y1 = 200;

x2 = 110;

y2 = 206;

*/

if((x1 >= x2) && (y1 >= y2)) {

temp = x1;

x1 = x2;

x2 = temp;

temp = y1;

y1 = y2;

y2 = temp;

}

dy = y2 - y1;

dx = x2 - x1;

if (dx != 0) m = (float)(dy/dx);

else m = -999;

// Debugging info

printf("\nDrawLine called!\n");

printf("x1 = %d\n", x1);

printf("y1 = %d\n", y1);

printf("x2 = %d\n", x2);

printf("y2 = %d\n", y2);

printf("dx = %d\n", dx);

printf("dy = %d\n", dy);

if (dx != 0) printf("dy/dx = %d\n", dy/dx);

printf("m = %.2f\n", m);

}

DrawLine called!

x1 = 286

y1 = 204

x2 = 309

y2 = 187

dx = 23

dy = -17

dy/dx = 0

m = 0.00
