People, this is so cognitive dissonance it's not even funny.

There is absolutely nothing obvious about 1/2 returning a number that
isn't at least approximately equal to one half.  There is nothing self-
evident about operations maintaining types.

You people can't tell the difference between "obvious" and "learned
conventions that came about because in limitations in the hardware at
the time".  Nobody would have come up with a silly rule like "x op y
must always have the same type as x and y" if computer hardware had
been up to the task when these languages were created.

I'd be interested in hearing what languages those are.
