Typical types

num := 3          // int
num := 3.         // float64
num := 3 + 4i     // complex128
num := byte('a')  // byte (alias for uint8)

Other Types

var u uint = 7        // uint (unsigned)
var p float32 = 22.7  // 32-bit float

<!-- Pointers -->

WARNING: Unported Hugo shortcode (manual conversion needed): {{< note size="medium" title="Pointers">}}

func main () {
  b := *getPointer()
  fmt.Println("Value is", b)

func getPointer () (myPointer *int) {
  a := 234
  return &a

a := new(int)
*a = 234

Pointers point to a memory location of a variable. Go is fully garbage-collected.
