Thanks, everyone, for the great input. I will continue to work thru the background readings and recommendations you graciously supplied and go from there. Best regards, - Don On Tue, 14 Jan 2020 at 07:04, Bruce O'Neel <bruce.oneel@pckswarms.ch> wrote:
HI,
I would upgrade that "a good read" to a critical read if you do anything with floating point. Floating point numbers are not real numbers but rather a small subset, and, have all kinds of funny properties. But we use them just like real numbers and that's what catches us out.
cheers
