What happens if you calculate 0.1 + 0.2 in different programming languages?

0.1 + 0.2 = 0.3, simple right? But here's the catch; computers store numbers in binary, not decimal. In the same way that 1/3 can't be precisely represented in decimal, 1/10 can't be precisely represented in binary, so it has to round off slightly. 00:00 - Title 00:06 - Python 02:24 - C Plus Plus 04:12 - C Sharp 05:53 - Java 08:08 - JavaScript 08:57 - Game Maker 10:22 - Scratch 11:29 - End screen Code: https://github.com/StefanGrace/ZeroPointOnePlusZeroPointTwo ♪ Music ♫ Song: Clarx - Zig Zag [NCS Release] Music provided by NoCopyrightSounds Free Download/Stream: http://ncs.io/ZigZag Watch: http://youtu.be/CLEWmT_8ppM Neon.Deflector - Outpost X https://neondeflector.bandcamp.com/track/outpost-x Jeremy Blake - A Rising Wave [YouTube audio library]
