Pitfalls of Floating-Point Numbers - Slides

Just as I announced in my previous blog post, today I gave a lecture on a "Kariera IT" event - organized by CareerCon, dedicated to IT jobs.

Here you can find slides from my presentation, in Polish. It's called "Pułapki liczb zmiennoprzecinkowych" ("Pitfalls of floating-point numbers").

Here are links to the Floating-Point Formats Cheatsheet (in English) that I mentioned in my presentation:

Wartości specjalne liczb zmiennoprzecinkowych mają zastosowanie w praktyce (pokaz slajdów sugeruje, że mają zastosowanie tylko czysto teoretycznie).

Przykład: jeżeli mamy zmienną A, ustawianą np. przez użytkownika i określającą maks. wartość zmiennej B, to użytkownik może przypisać zmiennej A wartość nieskończoności aby znieść jej ograniczenie na zmienną B.

Inny przykład: obliczamy współczynnik kierunkowy prostej. Jeżeli jest równy zero, to znaczy że prosta jest pozioma. Jeżeli jest równy nieskończoność, to znaczy że jest pionowa.
