divisions

(1/1)

Marten:
How can i divide 4/8 in c or 3/2 or things like that cause i always get 0.0000 when i use the following code:

float a=4/8;
printf("%f",a);

!?!?!? :cry:

TimoVJL:

--- Code: ---
#include <stdio.h>
#include <math.h>

int main(int argc,char **argv)
{
float a;
a=4/8;
printf("%f\n",a);  //0.000000
a=4.0/8;
printf("%f\n",a);  //0.500000
a=(float)4/8;
printf("%f\n",a);  //0.500000
return 0;
}

--- End code ---

cane:
Either:

--- Code: ---
float a=4.0/8.0;
printf("%f",a);

--- End code ---


--- Code: ---
float a=(float)4/8;
printf("%f",a);

--- End code ---

Marten:
Thanx !!!
