Basic types:
*Maps
*Type casting
Type casting
suggest changeUnlike a language like C, Go doesn’t do implicit casting between types.
You have to explicitly cast between compatible types:
// you can cast between numbers i.e. integers of various sizes and floating point numbers
var i1 int32 = 3
var i2 int = int(i1) // we must explicitly cast from int32 to int
var f float64 = float64(i1)
s := "string"
// we can cast between string and []byte and vice-versa
// note that unless optimizted by the compiler, this involves allocation
var d []byte = []byte(s)
Found a mistake? Have a question or improvement idea?
Let me know.
