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
方法一 时间戳: 1499389200 int64 方法二 时间戳: 1499389200 int64 时间戳对应字符串: 2017-07-07 09:00:00 string 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 参考
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 {...
Converting a float number into an integer number in Golang Problem Solution: In this program, we will convert 64-bit float number into 64-bit integer number using the int64() function and print the result on the console screen. Program/Source Code: The source code toconvert float number int...
