:But a digital computer can represent rational numbers exactly as you
:have (e.g. Smalltalk has a rational data type which behaves just
:like any other number) but irrational numbers cause problems. But
:then can an analogue machine represent irrational numbers exactly?
probably not, but even if it could, how would you measure it to
verify..? the strength of analogue is that it can vary smoothly, so the
errors are different in character. sometimes digital is preferable.
sometimes analogue is.
