如何将int转换为int64？

Im trying to convert an integer into an integer64 in go but im having no luck. Anyone know an easy way to do this?

This is called type conversion :

i := 23
var i64 int64
i64 = int64(i)

i := 23
i64 := int64(i)
fmt.Printf("%T %T", i, i64) // to print the data types of i and i64

This is probably obvious, but simplest:

i64 := int64(23)
