A Tour of Go If

The

if

statement looks as it does in C or Java, except that the

( )

are gone and the

{ }

are required.

(Sound familiar?)

package main

import (
"fmt"
"math"
)

func sqrt(x float64) string{
if x < 0 {
return sqrt(-x) + "i"
}
return fmt.Sprint(math.Sqrt(x))
}

func main() {
fmt.Println(sqrt(2), sqrt(-4))
}
