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, however, lay eggs. They are a species of primitive mammals called monotremes. Echidnas, or spiny anteaters, are the only other mammals that lay eggs. When the female platypus is ready to have her young, she will burrow down inside the ground on the riverbank and seal herself into one of her tunnel rooms.
