divitionof two int to a float number

hi,
i have a very weird problem.

i have two int that i divide them inside a subroutine and store the ratio to a float number. my problem is that after the division my int numbers changes to something complete different

Code (CSharp):

1. int width,height;
2. float ratio;
3.  
4. void Start(){
5. width =800;
6. height = 530;
7.  
8. giveratio(width,height);
9. }
10.  
11. void giveratio(int width, int height){
12. ratio = (float)width/float(height);
13. }
14.  

After running this i get :

ration = 1.5
and then the
width becomes 2500!
and height 1766!

what i am doing wrong here ?


UPDATE

found the error it was in onther part
