Ayrabhatta was a 6th century Indian mathematician who worked out π to about 5 decimal places. But it's been said that Chinese mathematicians in about the same era were able to work it out to about 5 to 7 decimal places. In any case, starting from the time Sumerians (or later the Old Babylonians) gave a crude approximation of 3 for π around 2500-2000 BC, successive peoples and mathematicians have improved on the accuracy somewhat steadily over the centuries. So, how is it decided when and who "discovered" the value of π ?
It's kind of like asking who discovered that the circle is round.
