Calculating the Pi Number

Engineer of Automated Data Processing and Control Systems. Graduated from Novosibirsk State Technical University (NSTU), Department of Automation and Computers.
I worked in television and developed broadcast automation systems.
I write programs in C/C++, Java, PHP, JavaScript, HTML, XML, CSS, MySQL.
I am interested in software architecture. Architecture is art. I use the style of modernism, in particular, it is cubism. Means the desire to parse the problem into the simplest modules. This solution allows you to assemble complex systems that surpass the complexity of the initial design concepts. I am the author of this programming technique.
