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.).
This is true and false.Most mammals do not lay eggs, but instead give live birth. There are, however, just two egg-laying mammals, which are members of the order Monotremata, so they are known as monotremes. Platypuses and echidnas are egg-laying mammals.
