Hi Bruno Marchal
Yes, you can square the square root of any number to test its
but there are a variety of algorithms used to calculate pi.
Which is correct ? See
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
