John Carmack Misremembers Pi

It is true, I incorrectly recalled the tenth digit of Pi. Happy #PiDay the Doom source code includes an incorrect approximation of pi as 3.141592657 instead of the correct 3.141592654. I hope someone got fired for that blunder #ifdef LINUX #include <math.h> #else #define PI #endif

John Carmack appears in a dark-mode social media post admitting that he incorrectly remembered the tenth digit of pi. A quoted Doom-related post points out an incorrect pi approximation in the source code, while the code image humorously shows a conditional definition of PI. The joke is a playful programming and Doom reference about a tiny numerical error being treated as a serious blunder.
