In an expression, the compiler treats an integer subrange type like an integer. Be careful with multiplying large numbers, particularly integers. The results of overflows are unpredictable. The real-number division operator, /, always produces a real- number result. For integer division, use the...
at all depending on the FPU exception mask) and only in case of integer divide by zero (div operation) an EDivByZero should be raised? This was my original question and no one seems to have an opinion onthat. I don't have an opinion on that either. I'm not sure how it would bete...
