Hello,
Apologies if I'm doing something stupid, but could someone please explain why 0.1+0.2-0.3 apparently equals 5.5511e-017?
If this is confirmed, I find it quite worrying, so are there other such "features" that may be quietly affecting my results without me being aware of them?
Many thanks, Jon.

In fact this is the most frequently asked question on here and CSSM.
