Converting from an Integer to hex is easy in Golang. Since a hex is really just an Integer literal, you can ask the fmt package for a string representation of that integer, using fmt.Sprintf(), and the %x or %X format.
package main import ( "fmt" ) func main() { for i := 1; i < 20; i++ { h := fmt.Sprintf("0x%x", i) fmt.Println(h) } } Golang Play
Output:
0x1 0x2 0x3 0x4 0x5 0x6 0x7 0x8 0x9 0xa 0xb 0xc 0xd 0xe 0xf 0x10 0x11 0x12 0x13 Convert back to int package main import ( "fmt" "strconv" ) var hex = []string{"1", "2", "3", "4", "5", "6", "7", "8", "9", "a", "b", "c", "d", "e", "f", "10", "11", "12", "13"} func main() { for _, h := range hex { i, _ := strconv.
