| As a consequence of their representation, most operations on numeric types are not true to their eponymous mathematical function. For example, adding two Int32 numbers can overflow, resulting in a wrong answer. Also, most floating point operations are not associative: (a + b) + c != a + (b + c). This is usually uncommon enough that it isn't a problem, but care should be taken to programming defensively. | As a consequence of their representation, most operations on numeric types are not true to their eponymous mathematical function.
