I have been looking for a program to calculate pi to a digit given
all I have seen so far are
why can't there be one to display PI to any amount of digits?
so I don't think it is possible for C basic C to compute pi.
In calculus the equation (at least, my way of getting the equation is right)
pi = 2 ( integral(sqrt(1-x^2)dx, from -1 to 1)
I derived this 2 years ago, I think there is also a series to do this but that is basically it right there.
If anyone finds a program to calculuate pi let me know. I would really appreciate it.
