Type conversions

Type conversions T(x) must be explicit and different types need to be compatible.

var f float64 = 1.2
// fraction is discarded
var i int = int(f)

var s string = "Hello World"
var r []rune = []rune(s)
var b []byte = []byte(s)

Package strconv

Conversions to and from string representations of basic data types.

// Integer To ASCII
s := strconv.Itoa(10)
// Equivalent to ParseInt(s, 10, 0)
i, err := strconv.Atoi("10")
