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.).
Egg-laying mammals are called monotremes. There are only three monotremes in the world: the long-beaked echidna, short-beaked echidna, and duck-billed platypus. The taxonomic family name for echidnas, Tachyglossidae, means âfast tongue.â Both male and female echidnas have a pouch on the belly, making it difficult to tell one from the other.
