golang 我无法转换“0x000000800”

Question

你好，我需要在转换此值“0x00000800”后输出1即使我将此值（“0x00000800”）转换为2048，也足够了。

fmt.Println(strconv.Itoa((0x00000800 >> 11) & 0x1F)) //working correctly

    

    //but my value comes as string

    src:= "0x00000800"

    fmt.Println(strconv.Itoa((src >> 11) & 0x1F)) //not working properly

伊托阿不是你要找的package mainimport (    "fmt"    "strconv")func main() {    fmt.Println(strconv.Itoa((0x00000800 >> 11) & 0x1F)) //working correctly    //but my value comes as string    src := "0x00000800"    // src[2:]   removes 0x    // base 16 hexadecimal    // bit size of int to convert to    fmt.Println(strconv.ParseInt(src[2:], 16, 64))}
