Re: Integer arithmetic in Java

[Russell Standish]

This is a well known feature of many languages, including C and
Fortran. I remember being flummuxed myself by this when I first came
across it in the late '80s, since my first computer language (Pascal)
actually produces a floating point number in the context (there exists
a special "div" operator to get integer truncation).

                                                Cheers
