|  |  | 
|  | ## chr | 
|  |  | 
|  | <pre> | 
|  | chr(<a href="#chr-i">i</a>) | 
|  | </pre> | 
|  |  | 
|  | returns a string encoding a codepoint | 
|  |  | 
|  | chr returns a string that encodes the single Unicode code | 
|  | point whose value is specified by the integer `i` | 
|  |  | 
|  |  | 
|  | **PARAMETERS** | 
|  |  | 
|  |  | 
|  | | Name  | Description | Default Value | | 
|  | | :------------- | :------------- | :------------- | | 
|  | | <a id="chr-i"></a>i |  position of the character   |  none | | 
|  |  | 
|  | **RETURNS** | 
|  |  | 
|  | unicode string of the position | 
|  |  | 
|  |  | 
|  | <a id="hex"></a> | 
|  |  | 
|  | ## hex | 
|  |  | 
|  | <pre> | 
|  | hex(<a href="#hex-number">number</a>) | 
|  | </pre> | 
|  |  | 
|  | Format integer to hexdecimal representation | 
|  |  | 
|  | **PARAMETERS** | 
|  |  | 
|  |  | 
|  | | Name  | Description | Default Value | | 
|  | | :------------- | :------------- | :------------- | | 
|  | | <a id="hex-number"></a>number |  number to format   |  none | | 
|  |  | 
|  | **RETURNS** | 
|  |  | 
|  | hexdecimal representation of the number argument | 
|  |  | 
|  |  | 
|  | <a id="ord"></a> | 
|  |  | 
|  | ## ord | 
|  |  | 
|  | <pre> | 
|  | ord(<a href="#ord-c">c</a>) | 
|  | </pre> | 
|  |  | 
|  | returns the codepoint of a character | 
|  |  | 
|  | ord(c) returns the integer value of the sole Unicode code point | 
|  | encoded by the string `c`. | 
|  |  | 
|  | If `c` does not encode exactly one Unicode code point, `ord` fails. | 
|  | Each invalid code within the string is treated as if it encodes the | 
|  | Unicode replacement character, U+FFFD. | 
|  |  | 
|  |  | 
|  | **PARAMETERS** | 
|  |  | 
|  |  | 
|  | | Name  | Description | Default Value | | 
|  | | :------------- | :------------- | :------------- | | 
|  | | <a id="ord-c"></a>c |  character whose codepoint to be returned.   |  none | | 
|  |  | 
|  | **RETURNS** | 
|  |  | 
|  | codepoint of `c` argument. |
