PI calculator in 146 bytes (boot sector or COM file) by Oscar Toledo G. Nov/11/2021 http://nanochess.org https://github.com/nanochess This is a simple program to calculate the PI digits. It can be run as a COM file or put into a boot sector of a floppy disk to be run. It's compatible with 8088 (the original IBM PC), and it will take a lot of time on a real hardware! ;) If you want to assemble it, you must download the Netwide Assembler (nasm) from www.nasm.us Use this command line: nasm -f bin pi.asm -Dcom_file=1 -o pi.com nasm -f bin pi.asm -Dcom_file=0 -o pi.img Tested with VirtualBox for Mac OS X running Windows XP running this program, it also works with DosBox and probably with qemu: qemu-system-x86_64 -fda pi.img Enjoy it! >> THE BOOK << Do you would like to learn 8086/8088 assembly language? Then get my book Programming Boot Sector Games and you'll also find a 8086/8088 crash course!
