minus-squareNeatNit@discuss.tchncs.delinkfedilinkarrow-up1·6 months agoTo be fair, it turns out not all environments implement floating-point arithmetic by the IEEE spec, meaning division by 0 can produce different results depending on where you run it. So in C++ float division by zero is undefined: https://stackoverflow.com/questions/42926763/the-behaviour-of-floating-point-division-by-zero But I’m fairly sure (note: based on literally no research) that most environments today will behave like the IEEE spec.
