How to fmt.Printf an integer with thousands comma

Question

Does Go\'s fmt.Printf support outputting a number with the thousands comma?

fmt.Printf(\"%d\", 1000) outputs 1000, what format

Answer 1

You can also use this small package: https://github.com/floscodes/golang-thousands.

Just convert your number to a string an then use the Separate-function like this:

n:="3478686" // your number as a string

thousands.Separate(n, "en") // adds thousands separators. the second argument sets the language mode.
