Agenda
- Warm-up: Which One Doesn’t Belong — four numeric results
- Compare and name it: How Numbers Actually Fit — why
0.1 + 0.2 != 0.3, and where the edges of every representation are - Money, deliberately: rebuild a price calculation that fails in floats, and fix it properly
Things to do before our next class
- Journal: one place in your own code that compares floats.
