A researcher has calculated the 2,000,000,000,000,000th digit of pi - and a few digits either side of it.

Nicholas Sze, of technology firm Yahoo, determined that the digit - when expressed in binary - is 0.

Mr Sze used Yahoo's Hadoop cloud computing technology to more than double the previous record.

The computation took 23 days on 1,000 of Yahoo's computers, racking up the equivalent of more than 500 years of a single computer's efforts.

The heart of the calculation made use of an approach called MapReduce originally developed by Google that divides up big problems into smaller sub-problems, combining the answers to solve otherwise intractable mathematical challenges.

At Yahoo, a cluster of 1,000 computers implemented this algorithm to solve an equation that plucks out specific digits of pi.
For God so loved the world, that he gave his only Son (Jesus Christ), that whoever believes in him should not perish but have eternal life. For God did not send his Son into the world to condemn the world, but in order that the world might be saved through him. Whoever believes in him is not condemned, but whoever does not believe is condemned already, because he has not believed in the name of the only Son of God. - John 3:16-18
