Square root of N

Question

Guys, I wrote a code, about getting the square root of any non negative number. But I am always getting close answers. I don't know if it's the only way or not. I don't want to copy other's codes. If I wanted I could have examined other's codes, but I wanted to know if you could fix my code without any dramatic changes.

Answer 1

Thnx, Kinshuk Vasisht. 👍

Answer 2

Thnx again.

Answer 3

You can try using taylor series to calculate more precise square roots.

The math remains the same.

Answer 4

You can read the formula from here : https://www.mathsisfun.com/algebra/taylor-series.html
The derivative of √x is 1/(2√x)

Answer 5

Here is a better process, without derivatives : burningmath.blogspot.com/2013/12/finding-square-roots-of-numbers-that.html?m=1

Answer 6

Jay Mathews, It's a nice code. But I'm interested in making the code without using any mathematical functions.

Answer 7

Thnx, hinanawi.

Answer 8

Here's my code https://code.sololearn.com/c5X3RnMAOx8q/?ref=app

Answer 9

Sadly, I don't know about Taylor series.
