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.).
Typically mammals are not egg laying. Thus, they do not hatch from eggs. However, here are two exceptions to the rule. These are the monotremes. The platypus and the echidna are monotremes, or mammals that lay eggs rather than give live birth.
