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.).
They belong to a sub-group of mammals that lay eggs rather than giving birth to live young (monotremes). When the first platypus was shipped to Britain from Australia, people thought it was a joke and that someone had sewn a duck's bill to a mammal's body.
