Daily WTF

A colleague of mine recently got a question from some one he’s working with on a big Java project at a company he’s stationed for the moment:

Q: if I have a Long with value 1615 and divide it with another long with value 1000, where did the numbers behind the . go ?

“als ik een long1=1615 deel door long2=1000, waar zijn mijn nummers na de comma naartoe?”
