Well, they did say to be exact, and you handed them approximations, so...

  Sure, but at the end of the day someone had to pay me an integer amount of cents. They wanted a total which was a normal dollar figure. But when you sum up 7.6 times whatever a whole lot, you might get a nice round number or you might get an irrational repeater. What's notable is clearly no one had actually thought this through at a policy level - the answer was "excel goes brrrr" depending on how they want to add up and subtotal things.

  The “exact” version they wanted was full of approximations too. They just didn’t have enough numerical literacy to understand how to say how much approximation they are ok with. I guarantee nothing in anyone’s time accounting system is measured to double-precision accuracy. Or at least, I’ve never quite figured out the knack myself for stopping work within a particular 6 picosecond window.
