If you do hashtable/hashmap on a language that has no fixed integer type... well yeah. But normally you'd like the data structures to map really well to the hardware. Pretty much all modern CPUs are two's complement ones - hence min integer is impossible to convert to anything else (having just the highest/sign bit, and rest zero)
