Floating point for money?!

- I've had that exact conversation with a friend in the past few weeks. All I can say is... I (at least) never think of the problems, or the alternatives. -- Eriksiers 20:44, 15 March 2010 (UTC)
- Two topics on the original wiki, Floating Point Currency and Money Object, contain many anecdotes, cautionary tales, and useful links. For a toy problem like this, using an integer in units of cents should suffice. --IanOsgood 01:29, 16 March 2010 (UTC)

However, (1) I'm the maintenance programmer, and (2) to work in integers would require a significant rewrite, something I have neither the time nor the patience for (I don't get paid for the work, and have to fit it in wherever and whenever possible.) --Axtens 02:30, 16 March 2010 (UTC)
