Answer 1

as per CostantinoGrana

"Do you know how IEEE 754 works? The numbers which you say "give 0" are multiples of a not too negative negative power of 2. So when you store them in little endian, the 32 less significant bits, that are all 0, are the first thing you find in memory as int. Your int is 32 bits wide, thus 0."
