Смысл: The text reports on the achievement of French programmer Fabrice Bellard, who used a personal computer to break the world record for calculating digits of Pi, surpassing records previously set by expensive supercomputers through the use of efficient algorithms.
Programmer Fabrice Bellard used a home PC and the Chudnovsky algorithm to calculate Pi to 2.7 trillion digits, beating previous supercomputer records.
Смысл: The text describes the achievement of a new world record in calculating Pi to 5 trillion decimal places, detailing the hardware, software (Chudnovsky formula), and verification methods used to surpass the previous record.
Engineers Alexander J. Yee and Shigeru Kondo broke the world record for Pi calculation by computing 5 trillion digits using a high-performance server over 60 days.
Смысл: The text describes a technical experiment to calculate pi using the Intel 4004 CPU to demonstrate the vast evolution of processor performance and the challenges of low-level programming on extremely constrained hardware.
The author successfully programmed an Intel 4004 microprocessor to calculate pi, taking over 3 hours to achieve what modern CPUs do in milliseconds.
