Pi: the area of a circle. Pi is a never ending number. (3.1415926535...) A Japanese supercomputer once calculated 3 trillion digits of pi. Ten years later an American supercomputer found 6 trillion digits of pi proving it was never ending.
A normal computer usually takes exactly 2.341 seconds to compute the first 1 million digits of pi. A supercomputer on the other hand takes 1.267 seconds to compute pi. For a Mac, it takes 2.231 seconds.
more that 50 digits.

Nobody is responsible. Different groups have decided, on their own, to calculate pi to many digits - as a sort of challenge.
Because Pi is known to be an irrational number it means that the digits never end or repeat in any known way. But calculating the digits of Pi has proven to be an fascination for mathematicians throughout history. Some spent their lives calculating the digits of Pi, but until computers, less than 1,000 digits had been calculated. In 1949, a computer calculated 2,000 digits and the race was on. Millions of digits have been calculated, with the record held (as of September 1999) by a supercomputer at the University of Tokyo that calculated 206,158,430,000 digits. (first 1,000 digits). However, learning 3.141, is all that is necessary. But you can go on and on, to infinity, and never find the exact circumference of a circle. I have only memorized 205 digits of pi; and yes I do use it to find the circumference of a circle.

There are several infinite series. To find PI to x digits, evaluate each term to x+2 digits until the value is 0. Then round to x digits.
The square root of 5 is approximately 2.236. It is an irrational number meaning we can not calculate its value no matter how many digits we can find. At one point a NASA computer was used to calculate the first million digits of the number.
The significant digits of a number represent a count of digits and so are represented by an integer. Any integer can be written in fractional form.
you only need 3.14 for the circumfrence of a circle
