Non-decimal radices/Convert: Difference between revisions

{{task}}[[Category:Number Base Conversion]]Number Basebase Conversionconversion is when you express a stored integer in aan numberinteger base, such as in octal (base 8) or binary (base 2). It also is involved when you take a string representing a number in a given base and convert it to the stored integer form. Normally, a stored integer is in binary, but that's typically invisible to the user, who normally enters or sees stored integers as decimal.

Write a function (or identify the built-in function) which is passed a non-negative integer to convert, and another integer representing the base. It returnsshould return a string containing the digits of the resulting number, without leading zeros except for the number 0 itself. For the digits beyond 9, one should use the lowercase englishEnglish alphabet, where the digit a = 9+1, b = a+1, etc. The decimal number 26 expressed in base 16 would be 1a, for example.

Write a second function which is passed a string and aan integer base, and it returns an integer representing that string interpreted in that base.
