For the first time mathematicians were able to calculate the Pi constant with 10 trillion decimal digits.

Ten trillion would represent a 1 with 13 zeros. If you were to print that number on paper, you would need about 2.87 billion sheets, based on a standard configuration of about 3500 digits per sheet. Such a stack of paper would reach a height of 21.4 miles.

According to an unofficial announcement the calculation of the 10 trillion digits, it took 371 days and an additional 45 hours to verify on a system equipped with two Intel Xeon X5680 processors, 96 GB of memory and 24 2 TB hard drives. Only the first 5 trillion are offered for download as decimals via five separate downloads totaling 1.91 TB at this time.

The record of 10 trillion records doubles the previous record of 5 trillion digits, which was posted in August of this year.
