How I can Find square root in c++ without sqrt and cmath?

Question

I need to find square root in c++ without use any Functions any one can tell me?

Answer 1

You could implement the babylonian method

next = (prev - num/prev)/2

Iterate that until either 'next' and 'prev' are near enough or 'next' and 'num' are

Where 'num' is the number you want the sqrt of

This method will always approach the +sqrt from above with positive initial guesses,
and -sqrt from below with negative initial guesses

The closer the initial guess is from the root the better

1 and num are equally good initial guesses
