How can 0.1 + 0.2 go wrong in my code?
🎤Our colleagues Andreas Herten and Edoardo Di Napoli were recently featured on the CodeForThought Podcast episode “ByteSized: Fun with Floating Points”. They explore how real numbers are actually represented on computers – and what can go wrong. From the evolution of floating-point formats and the IEEE standard to today’s shift toward lower precision, the episode sheds light on why these choices matter more than ever. 🎧https://codeforthought.buzzsprout.com/1326658/episodes/18841644-en-bytesized-fun-with-floating-points-u-ruede-a-herten-and-e-di-napoli
