At the very least, not to many programmers.  It's the same behaviour
in C:


> cat > tmp.c
#include <stdio.h>
main() {
 int i=7, j=2;
 float x=7.0f, y=2.0f;

 printf("i==x : %d\n", i==x);
 printf("j==y : %d\n", j==y);
 printf("i/j==x/y : %d\n", (i/j)==(x/y));
}
> /usr/local/bin/gcc tmp.c
> ./a.out
i==x : 1
j==y : 1
i/j==x/y : 0
