How to change int in int64?

Question

Im trying to convert an integer to an integer 64 in go, but they are out of luck. Does anyone know an easy way to do this?

Answer 1

This is called a type conversion :

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

Answer 2

This is probably obvious, but the simplest:

 i64 := int64(23) 

Answer 3

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