I was doing (int64)i, it din't work, old habit from clang. This reverse from C++ worked. – Manohar Reddy Poreddy Jul 29 '15 at 09:35

This is probably obvious, but simplest:

i64 := int64(23)

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

is it possible to use `LL` as postfix like c/c++? – Mayur Jan 10 '20 at 09:45
