我如何从int转换为hex

Question

I want to convert from int to hex in Golang. In strconv, there is a method that converts strings to hex. Is there a similar method to get a hex string from an int?

Answer 1

Since hex is a Integer literal, you can ask the fmt package for a string representation of that integer, using fmt.Sprintf(), and the %x or %X format.
See playground

i := 255
h := fmt.Sprintf("%x", i)
fmt.Printf("Hex conv of '%d' is '%s'
", i, h)
h = fmt.Sprintf("%X", i)
fmt.Printf("HEX conv of '%d' is '%s'
", i, h)

Output:

Hex conv of '255' is 'ff'
HEX conv of '255' is 'FF'
