A Tour of Go. Advanced Exercise: Complex cube roots. Let's explore Go's built-in support for complex numbers via the complex64 and complex128 types. For cube roots, Newton's method amounts to repeating: Find the cube root of 2, just to make sure the algorithm works. There is a Pow function in the math/cmplx package.
package main
import (
"fmt"
"math"
"math/cmplx"
)
func Cbrt(x complex128) complex128 {
z := complex128(1)

A Tour of Go. Exercise: Loops and Functions. As a simple way to play with functions and loops, implement the square root function using Newton's method. In this case, Newton's method is to approximate Sqrt(x) by picking a starting point z and then repeating: To begin with, just repeat that calculation 10 times and see how close you get to the an…
package main
import (
"fmt"
"math"
)
func Sqrt(x float64) float64 {
z := 1.0
for i := 1; i <= 10; i++ {
