I'm looking for an efficient tool that can help me approximate the square roots of large numbers to the nearest integer. (By large, I'm talking about numbers with several hundred digits.) Other than that, I don't really have any further constraints - it could be online or available as a download. Does anyone know where I could find one?
I've seen methods listed online, but those can get quite tedious after a while. I've also seen algorithms listed online, but I don't have the software needed to run the code and I don't want to spend money on it.
Thanks in advance!
