In 2022, Google Cloud Developer Advocate Emma Haruka Iwao announced that she and her team had calculated the value of pi to a precision of 100 trillion decimal places—a flex on her previous record of 31.4 trillion digits, set in 2019. "We were impressed by the achievement of Emma and the...
As pi is an irrational number, the digits after its decimal point are never-ending. In order to use the value of pi in day-to-day calculations, various approximations of the value of pi are used. One of these approximations is the value 3.14. Thus, 3.14 is often said to be the value...
Pi is an irrational number, which means that it is a real number that cannot be expressed by a simple fraction. That's because pi is what mathematicians call an "infinite decimal" — after the decimal point, the digits go on forever and ever. Students are usually introduced to the number...
Pi is a rare number that has 31.4 trillion decimal place values and counting! When doing math with pi, mathematicians definitely don’t use 31.4 trillion decimal places. They round pi down to a more manageable number. At NASA, pi is rounded down to 15 digits: 3.14159265358979. Let’s try...
After those three famous digits comes an endless "irrational" sequence without permanent patterns or repeating sections. Even though the sequence continues indefinitely, pi enthusiasts have made hobbies out of memorizing and reciting as many decimal places as possible. The Guinness World Record is70,...
Another way to measure the difference between a floating-point number and the real number it is approximating is relative error, which is simply the difference between the two numbers divided by the real number. For example the relative error committed when approximating 3.14159 by 3.14 × 100 ...
