Type Conversion

Go uses explicit conversions when a value needs a different type.

package main

import "fmt"

func main() {
	var whole = 
	half := float64(whole) / 2.0
	label := fmt.Sprintf("%.1f", half)

	fmt.Println("whole=", whole)
	fmt.Println("half=", label)
}

package main

import "fmt"

func main() {
	var whole = 
	half := float64(whole) / 2.0
	label := fmt.Sprintf("%.1f", half)

	fmt.Println("whole=", whole)
	fmt.Println("half=", label)
}

package main

import "fmt"

func main() {
	var whole = 
	half := float64(whole) / 2.0
	label := fmt.Sprintf("%.1f", half)

	fmt.Println("whole=", whole)
	fmt.Println("half=", label)
}

type conversion A conversion such as `float64(value)` creates a value of the target type.
