Functions

func ByteToFloat32

func ByteToFloat32(bytes []byte) float32

BytesToUint16 converts a little endian array of bytes to an array of unit16s

func CheckPwd

func CheckPwd(reqPwd, dataPwd string) error

不同数据的加密值一定不同，相同数据的加密值一定相同，因此，在处理用户登录时只需要对用户传递的密码做加密处理，并与原加密值做比较是否一致即可

func DownRounding

func DownRounding(f float64, accuracy int) (r float64)

保留小数 向下取整

func Encrypt

func Encrypt(password string) (encryptPwd string)

MD5单向加密

func FatalOnError

func FatalOnError(err error, msg string, data ...interface{})

func MapRound

func MapRound(m map[string]interface{}, accuracy int)

将map中的float值进行舍入

func NewLen

func NewLen(length int) string

func NewLenChars

func NewLenChars(length int, chars []byte) string

NewLenChars returns a new random string of the provided length, consisting of the provided byte slice of allowed characters(maximum 256).
