Another class of bugs silently transfers fractions of a cent into a bank account... I did, personally, once have a bug in a script while working in finance, once upon a time. Working on a portfolio of test contracts with trillions of dollars in notional value, and I was off by a single penny. It was an easily found and fixed one-line bug due to truncation instead of correct rounding. But, yes. $1e-2 off on a portfolio worth $1e12 was enough to block release.
