Category:Convert Integer to String
This category's articles describe functions that take a integer argument and return a string. For example 99 becomes ninety-nine. This is more challenging than it might at first appear, particular because of the internationalization and localization issues. For example 129 in German is Einhunderdneunundzwanzig and in French is cent vingt neuf and there are often lots of irregularites and special cases. Even in English, which is reasonably regular, there are surprising localization issues. For example, in the USA 129 is pronounced one hundred twenty-nine, whereas an English person would say one hundred and twenty-nine.
A library function that solves this problem in a given programming language would be useful in refining the solution of 99 Bottles of Beer.hijackerhijacker
