> When the variable range is a signed integer, then the expression -range % range is zero. In a programming language with only signed integers, like Java, this expression is always zero.
Not because of your intuition on the quotient. E.g. try -8 % 5, -8 % 6, and -8 % 7 and this feeling of perfect sense compared to the languages with unsigned types should melt away.
