Jan 20, 2022 · I need to calculate the square root of some numbers, for example √9 = 3 and √2 = 1.4142. How can I do it in Python? The inputs will probably be all positive integers, and relatively small (say less...

In Python this operation seems to be represented by the ** syntax. >>> 3**2 9 If I want to go the other direction and calculate the 2nd root of 9 then in maths I need to use a symbol: 2√9 = 3 Is there a short-hand symbol in Python, similar to ** that achieves this i.e. 2<symbol>9? Or do I need to use the math module?

Jun 15, 2010 · I want to find the square root of a number without using the math module,as i need to call the function some 20k times and dont want to slow down the execution by linking to the math module each ti...

Mar 13, 2013 · Is there an integer square root somewhere in python, or in standard libraries? I want it to be exact (i.e. return an integer), and raise an exception if the input isn't a perfect square. I tried u...

Mar 22, 2010 · How could I check if a number is a perfect square? Speed is of no concern, for now, just working. See also: Integer square root in python.

Sep 17, 2018 · The question is To find the square root of number ‘N’.using this procedure, we must implement the following process: Guess a value for the square root of N Divide N by that guess Average the resul...

I have run across some confusing behaviour with square roots of complex numbers in python. Running this code: from cmath import sqrt a = 0.2 b = 0.2 + 0j print (sqrt (a / (a - 1))) print (sqrt (b / (...

Jul 17, 2017 · Python is not an equation solver, like Wolfram Alpha. It is a language that executes the instructions you give it. root = number**(1/2) is an instruction. It says: take number, which already exists, and raise it to the 1/2 power; name the result root. number = root**2 is also an instruction, but not the one you want.

Sep 13, 2017 · How can one find the square root of a number without using any pre-defined functions in python? I need the main logic of how a square root of a program works. In general math we will do it using HCF but in programing, I am not able to find the logic.
