Go 語言將 unit 類型轉成 string

1func sprint(u uint) string {
2    return fmt.Sprint(u)
3}

1func formatUint(u uint) string {
2    return strconv.FormatUint(uint64(u), 10)
3}

 1func BenchmarkSprint(b *testing.B) {
 2    for n := 0; n < b.N; n++ {
 3        sprint(uint(n))
 4    }
 5}

 9        formatUint(uint(n))
10    }
