The quest for precision in pi has led to over 2.7 trillion digits calculated, but how many do we actually need? This exploration contrasts mathematicians’ obsession with engineers’ practical approach.

For math lovers around the world, March 14 is a holiday, "Pi Day." That's because the date — 3/14 — is also the beginning of the decimal expansion of the world's best-known irrational number ...

The latest computation of pi was 3.5 times as fast as the previous effort, despite the extra 12 trillion decimal places – an impressive increase in supercomputing performance in just 18 months.

The value of pi – the ratio of a circle’s circumference to its diameter – has been calculated anew on a super computer, adding 12.8 trillion new decimal digits to its roster, for a total of ...

Researchers are set to break the world record for the most precise value of pi, after using an advanced computer to calculate the famous constant to 62.8 trillion decimal places.

Researchers at the University of Tsukuba, Japan, have demolished the previous world record on the constant pi, more than doubling the amount of decimals to 2.5 trillion. They used a massive ...

Most of us can give Pi to four or five digits, but Swiss scientists have broken the world record. It took three and a half months and a data center’s worth of computer equipment, but the ...
