Long story short: not every single real number have an *exact*
representation in the computer. You have to live with that and learn the
limitations and pitfalls of floating point calculations.

It might be the case (I didn't do the math) that 999.999 doesn't have an
exact representation in IEEE-754 double-precision format, so the best you
get is an aproximation (a pretty good one, btw).

Congratulations for such initiative. Very nice. I hope this helps
Lazarus/FPC to get more visibility.
Just one point: I'd strongly recommend you provide a build with
stable/production versions of Lazarus and FreePascal. They are the best the
Lazarus/FPC team can offer and they have production qual

Hi
I'm not sure if you guys are aware of this but here it goes.
A brazilian publisher named Editora Erica (www.erica.com.br) published
a brand new book about introdutory computer programming with
FreePascal.
