The error seems to be coming from https://github.com/hexon/mysqltsv/blob/2b86f827d04d8756e4837073ecf512595e49bc90/mysqltsv.go#L213C2-L213C9 . I do not see float is being handled anywhere.

Adding the following line at (https://github.com/hexon/mysqltsv/blob/2b86f827d04d8756e4837073ecf512595e49bc90/mysqltsv.go#L213C2-L213C9)](https://github.com/hexon/mysqltsv/blob/2b86f827d04d8756e4837073ecf512595e49bc90/mysqltsv.go#L213C2-L213C9) fixes the issue for float64. We have to handle all the other variants of float.

case float64:
    return []byte(strconv.FormatFloat(v, 'f', -1, 64)), nil
