How can I find the Square Root of a Java BigInteger?

Question

Is there a library that will find the square root of a BigInteger? I want it computed offline - only once, and not inside any loop. So even computationally expensive solutio

Answer 1

you can also use binary search to find the square root of x also you can multiply it to for example 10^10 and find an integer like m by binary search since m^2

System.out.println(m.divide(10^5)+"."+m.mod(10^5));
