San Francisco (CNN Business) A Google employee has broken the world record for calculating pi just in time for the mind-bogglingly long number's special day. Her milestone was certified by Guinness World Records on Wednesday, making her the third woman to set a world record for calculating the number. Iwao broke the record for pi set by Peter Trueb in 2016, which was 22.4 trillion digits long. "It was my childhood dream, a longtime dream, to break the world record for pi," Iwao told CNN Business. Her former professor and one time world record holder for pi, Daisuke Takahashi, helped her with advice and technical strategies.
