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.).
There is only one other egg-laying mammal in the world. The echidna, a distant cousin of the anteater, also lays eggs and is found in Australia and New Guinea. Both the platypus and the echnida are monotremes, meaning that they lay eggs and have a single opening (cloaca) for reproduction and elimination of wastes.
