Learn the RESHADED framework for architecting web-scale applications by determining requirements, constraints, and assumptions before diving into a step-by-step design process.

We use the cbrt() method in Julia to find the cube root of a value. Below is a mathematical representation of the cbrt() method:

cbrt(x)=x1/3cbrt(x)=x^{1/3}

The code snippet below shows how to use the cbrt() function in Julia.

cbrt(x::Real)

The cbrt() method accepts one argument, x, which is the number for which the user seeks the cube root. The above line will return the cube root of x.

Note: x must be a real number.

Example

Let’s run a script that uses the cbrt() method.

## Find the cube root of 27
println( "cbrt(27) => $(cbrt(27))")
## Find the cube root of 125
println( "cbrt(125) => $(cbrt(125))")
## Find the cube root of 27.27
println( "cbrt(27.27) => $(cbrt(27.27))")
Hit "Run" to see the cbrt() function in action. Change the values being passed to the cbrt() function and observe the results.

Explanation

  • Line 2: We use the cbrt() method with 27 as an argument. cbrt(27) returns 3.
  • Line 5: We use the cbrt() method with 125 as an argument. cbrt(125) returns 5.
  • Line 8: We use the cbrt() method with 27.27 as an argument. cbrt(27.27) returns 3.0099668506262676.
