function, available since PHP 4. Go supports conversion to string to different bases from 2 up to 36 using the built-in strconv.FormatInt(), and strconv.FormatUint() functions, and conversions from string encoded in different bases from 2 up to 36 using the built-in strconv.ParseInt(), and strconv.ParseUint() functions. Python allows conversions of strings from base 2 to base 36.
