Float can contain up to seven digits in total, not just following the decimal point â so, for example, 321.1234567 cannot be stored in float because it has 10 digits. If greater precisionâmore digitsâis necessary, the double type is used.
This animal may have sharp spines, but it isn't a porcupine! It's one of two types of primitive egg-laying mammals, or monotremes. (The other is the duck-billed platypus.).
Platypuses are mammals, but not marsupials (pouched mammals). They are monotremes, that is, egg-laying mammals. After a short gestation period, the mother lays an egg containing the baby.About ten days later, the egg hatches, and the baby emerges.Marsupials also have short gestation periods, but after it is done, there is live birth.lthough a mammal with a pouch is always a marsupial (with the exception of the echidna, which develops a rudimentary pouch during breeding season), not all marsupials have pouches, for example, the numbat of Western Australia. All marsupials are mammals, but not all mammals are marsupials.
