How to Take the Square Root Of A Number In Elixir?

3 minutes read

In Elixir, you can use the :math.sqrt/1 function to take the square root of a number. This function takes a single argument, which is the number for which you want to calculate the square root.


Here's an example of how you can use this function:

1
2
3

number = 16
square_root = :math.sqrt(number)
IO.puts("The square root of #{number} is #{square_root}")


In this example, we're calculating the square root of the number 16 and then printing the result using IO.puts(). You can use this same function to calculate the square root of any number in Elixir.


How to find the cube root of a number in Elixir?

In Elixir, you can find the cube root of a number using the :math.pow/2 function, which raises a number to a specified power. Here's how you can find the cube root of a number using this function:

  1. Import the :math module:
1

import :math


  1. Calculate the cube root using :math.pow/2 function:
1
2
3
4

number = 27
cube_root = round(pow(number, 1/3))

IO.puts "The cube root of #{number} is #{cube_root}"


In this example, we are finding the cube root of the number 27. The 1/3 power is used to find the cube root. The round function is used to round the result to the nearest whole number.


Run this code in an Elixir environment, and you will see the cube root of the given number printed to the console.


What is the square root of a complex conjugate in Elixir?

In Elixir, you can calculate the square root of a complex number by using the :math.sqrt/1 function from the :math module. Here is an example to calculate the square root of a complex conjugate:

1
2
3
4

number = 5 + 8i
conjugate = Complex.conj(number)
result = :math.sqrt(conjugate)
IO.puts result


In this example, number is a complex number, and conjugate is its complex conjugate. The :math.sqrt/1 function is then used to calculate the square root of the conjugate.


What is the maximum size of a number that can be used with the square root function in Elixir?

The maximum size of a number that can be used with the square root function in Elixir is dependent on the underlying number representation used by the language. In Elixir, numbers are represented using the float data type, which is a double-precision floating-point number with a maximum size of approximately 1.7976931348623157E+308. This means that you can take the square root of numbers up to this maximum size using Elixir's square root function.


How to round the square root to the nearest whole number in Elixir?

One way to round the square root to the nearest whole number in Elixir is to use the round function from the Kernel module. Here's an example code snippet that demonstrates how to do this:

1
2
3
4

number = 16
square_root = round(:math.sqrt(number))

IO.puts("Square root of #{number} rounded to the nearest whole number: #{square_root}")


In this code snippet, we first calculate the square root of the number 16 using the :math.sqrt function. Then, we use the round function to round the square root to the nearest whole number. Finally, the result is printed to the console.
