Two Case Studies of NaN
This article explores how the IEEE-754 'Not a Number' (NaN) value creates unexpected behavior in programming languages like Python and Lua. It demonstrates how implicit assumptions about equality and iteration logic fail when encountering NaN.
Why it matters
Understanding these edge cases is critical for developers to prevent bugs in numerical computing and data processing.
IEEE-754 NaN is weird. and because of that, it's often accidentally left unaccounted for. i found two instances of this leaking into programming language design. that is, the semantics of these languages hold implicit assumptions which break with NaN.
