The thing is, making 1/2=0.5 won't make the problem *worse*. Because
after two days of being baffled by 1/2=0, these newbies will eventually
figure out the solution float(1)/2. So, I'm just getting to show them
the buggy roundoff-error code *faster*, instead of making them suffer
for it. You want to fix *that* problem, you have to give easy to access
