Ok, maybe a non-question.

The very first CAD package that I used, Draft Choice for Windows since you ask, claimed that regardless of the displayed precision, its internal precision was something like 15 or 16 decimal digits. In other words, say you set it to calculate pi, but only display 2 decimal digits, ie 3.14, the program would actually calculate to a depth of 15 or 16 decimal digits regardless of the displayed value.

I know that DC17 can be set to display various depths of decimal digits, but have not found anything to tell me what the actual calculation depth is. Any ideas anyone?

Incidently, it's only for interest.
