Question

In the 2011 lecture 3 they make a program that gives you a number that is CLOSE to the square root of a number. How can I make a program in python that finds the exactly square root of any number (int/ float)?

Answer 1

You could make epsilon extremely small, but to get an exact square root means python has to do ALOT of calculations so it would take a very long time to get anywhere. There is probably a way to do it but in my opinion the best way, if you want a very precise answer is to simply use a very small epsilon. I know im not exactly answering your question but i hope this helps

Answer 2

or just use the sqrt() function in the math module.

Thank you both!
