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.).
Most reptiles lay eggs, but in a few snakes and lizards, the eggs develop inside the motherâs body so that she gives birth to live young. Crocodiles and tortoises lay hard-shelled eggs similar to birdâs eggs. Turtules, snakes, and most lizards lay eggs with softer leathery shells. Sea turtles lay their eggs on beaches.
