Go has several integer types: uint8, uint16, uint32, uint64, int8, int16, int32 and int64. But strconv only support 3 of them which is int, int64 and uint64. So let's see how to use it. Parse string to int func main() { res, err := strconv.Atoi("10") if err != n...
Type:string,Value:123 Go Copy strconv.FormatInt()函数 strconv包提供了另一个称为FormatInt()的函数,用于将整数变量转换为字符串。此函数需要两个参数:整数值和数字系统的基数。 示例 packagemainimport("fmt""strconv")funcmain(){num:=int64(123)str:=strconv.FormatInt(num,10)fmt.Printf("Type: %...
type saveLog func(msg string) //这个函数的第二个参数是一个函数 //这个函数将一个字符串转换为Int类型,如果失败了,则返回0,并输出错误。 func stringToInt(s string, log saveLog) int64 { if value, err := strconv.ParseInt(s, 0, 0); err != nil { log(err.Error()) return 0 } else {...
