Hi Bruno MarchalYes, you can square the square root of any number to test itsaccuracy,but there are a variety of algorithms used to calculate pi. Which is correct ? See http://en.wikipedia.org/wiki/Pi The value obtained is assumed to be true if the infinite series used to calculate pi converges. But I would think that many if not most infinite series should converge. Which one is the right one ? Is there a unique solution ?

`Most series would not converge. In this case they all converge to Pi,`

`as they have been designed for that. Some just converge more quickly`

`than others.`
