want algorithm details

[Guest]

hi, how can i take squre root of a number which is 300+ digits long in VC++.
is there any .net class that provide this functionality. I know that
in C i have to implement my own data structure( link list ) but have
anybody exact idea how can i achieve this

There is a method to take square roots manually (I don't recall the
details here but it involves pairing up digits in the number). You may
have to implement that.

ask in sci.math.num-analysis, also check books such as Numerical Recipies In
C.

www.oonumerics.org should have a suitable arbitrary precision library.
