Converts an integer to a string value. String representations for radixes above 10 use the letters ‘a’ through ‘z’ for the digits from 10 to 35. So hexadecimal numbers would use [0-9] and [a-f], and base 20 would use [0-9] and [a-j], and base 36 would use all the alphanumeric characters.

| digit | An instance of <integer>. |
| base: | An instance of <integer>. Between 2 and 35, inclusive, representing the radix of the string representation. The default base is 10. |
| uppercase: | An instance of <boolean>. For #t, returns uppercase letters for digits greater than 10, and for #f, lowercase letters. The default is #f. |
