Named Return Values

Return values can be assigned to a local variable. An empty return statement can then be used to return their current values. This is known as "naked" return. Naked return statements should be used only in short functions as they harm readability in longer functions:

func Inverse(v float32) (reciprocal float32) {
    if v == 0 {
    reciprocal = 1 / v

//A function can also return multiple values
func split(sum int) (x, y int) {
    x = sum * 4 / 9
    y = sum - x

Two important things must be noted:

  • The parenthesis around the return values are mandatory.
  • An empty return statement must always be provided.
