Bug ? It's a direct mapping to the libc function, strfmon [1], and an equivalent C script gave the same result so it's not a bug in PHP. Locales can't define rounding rules, so it's not related to that. Googling for strfmon rounding errors doesn't get any useful results, so either this is by design or it's never caused anyone a problem. Solution... pass the number through round before going in to money_format. -Stuart -- Stuart Dallas 3ft9 Ltd http://3ft9.com/
