An educational website (0.30000000000000004.com) explaining why floating point math produces results like 0.1 + 0.2 != 0.3, with the underlying binary representation theory. It collects code examples showing the output of 0.1 + 0.2 across dozens of programming languages.
Use cases
- explain why 0.1 + 0.2 does not equal 0.3
- look up floating point behavior in a specific programming language
- teach students about IEEE 754 and binary fractions
- find examples of floating point precision issues across languages
- understand why computers have decimal rounding errors
When to choose
- you need a quick, beginner-friendly explanation of floating point inaccuracy
- you want to compare how different languages print 0.1 + 0.2
- you are teaching or learning about binary number representation
When to avoid
- you need a library for exact decimal arithmetic rather than an explanation
- you need deep, rigorous coverage of IEEE 754 beyond the basics
