Thread: Int to Float

I've tried to do this:

Code:

#include <stdio.h>


int main() {
int a=3,b=2;
float c;

c = (float)(a/b);
printf("%f\n",c);

return 0;
}

But instead of 3/2 he returns 1.00000000...

How can i convert Int to float?

Thanks!

is there any error here:

Code:

xmax = (((float)x1 + ((float)wire_data[0] /2)) > xmax) ? ((float)x1 + ((float)wire_data[0] /2)) : xmax;

xmin = (((float)x1 - ((float)wire_data[0] /2)) < xmin) ? ((float)x1 - ((float)wire_data[0] /2)) : xmin;
ymax = (((float)y1 + ((float)wire_data[0] /2)) > ymax) ? ((float)y1 + ((float)wire_data[0] /2)) : ymax;

ymin = (((float)y1 - ((float)wire_data[0] /2)) < ymin) ? ((float)y1 - ((float)wire_data[0] /2)) : ymin;

I think it's okay.

Hey guys, sorry to bring back an old thread but I'd rather do this than start a new one!

I'm basically having trouble converting an int to a float. I've tried the following code and ever single time floatadd = 1077280768

Code:

floatadd = newadd;

Code:

floatadd = (double)newadd;

Code:

floatadd = double(newadd);

I.e I've tried every option I've seen listed around here. Newadd is 22 and I need to convert it to a floating point to do some jazz on it, but all the above give 1077280768 as an answer. Any ideas?

I'm sorry if this is a noobie question, I am very new to C programming.

Thanks,

Thanks Pete, I realise float and double are different, I just copied and pasted the same thing 3 times above. Found the problem, turns out I'm a complete idiot and used %d in the printf command. Oh well... Stared at the convert line for ages without ever looking at the printf. Sorry!
