... Especially when you subtract two nearly equal numbers.
Computers do, but do no programming environments take account of
this, by marking recurring numbers as such?
Anyone know how Mathematica works?

Ronn--
I believe it avoids decimal approximations unless they are
specifically asked for. Rational numbers would always be
represented internally as pairs of integers. And this
continues; almost everything is represented symbolically.
So (1 + sqrt(2))^2 is exactly 3 + 2*sqrt(2), etc.
