What is a recursion square root of a number?

Answer by  Mac44 (479)

A recursive square root algorithm makes multiple guesses about the square root of a number until it finds a value that is deemed "close enough. "

Recursion square root is a technique to find the square root of a number. This technique starts with a guess of the number's square root. A comparison is done to see how close the guess is to the actual square root (simply square the guess and compare it). Depending on the comparison, continually modify the guess until its close enough.
