I work for a large Australian government department that is charged with the responsibility of distributing of TENS OF BILLIONs of dollars of taxpayers' money. My unit is the data analysis unit. The following conversation really took place, and is fairly typical of the calibre of conversations in my unit.
Manager of unit walks out of her manager's office (call him Bigwig) over to underling's desk (call him Underling), looks around and leans over speaking in a low voice out of the corner of mouth.
Mgr: "Underling, integers have decimal places don't they? Bigwig's trying to tell me they don't. He's wrong isn't he?"
Underling: (squirming) "...ah..no..."
Mgr: "Well hang on, they CAN have decimal places, can't they?"
Mgr: "...but in some cases they can, right?"
Underling: "Don't think so."
Mgr: (annoyed) "Well why not? What's wrong with an integer having decimal places? Why can't 1.3 be an integer?"
Underling: "There's nothing wrong with 1.3 having a decimal place..."
Mgr: "So that's OK?"
Mgr: "See I knew it..."
Underling: "...it's just not an integer..."
Mgr: "Hmm I still don't think that's right. Can you quickly check through the data and see whether any of our integers have decimal places? I'm sure Bigwig's wrong."
Underling: "Yep, sure. Could take a few days. We have a lot of data."
Mgr: "Thanks Underling."
