As a computer science student I attend a math class at university where we not only use real numbers, but also other algebraic fields, the so-called finite fields. As opposed to the real numbers, finite fields only have a finite set of numbers. When performing the mathematical operations +, -, * or / on elements from this limited set of numbers, it is not possible to "break out" of it, i.e. the result is an element of...
