If you’ve ever used pi in math class, you probably used the number 3.14. In fact, the number for pi is much longer. Pi is called an irrational number (无理数) because the digits (数位) after the decimal point (小数点) never end or repeat. In 2015, a young man from India named...

Since integers are stored in the computer as base 2 numbers 32 digits long, all the leading 0’s turn into 1’s. See also LOGAND, LOGOR, and LOGXOR.ExampleThe number 21 in binary notation would be21 = 00000000000000000000000000010101
