If the prefix is 0 and "x", it is interpreted as the hexadecimal nu

1. Basic typesThere are several basic data types for Javascript: Number String: Boolean: Undefined: When you access a non-existent variable, you get it undefined . It is also available when you define a variable but do not assign it a value undefined . JavaScript automatically initializes the variable to that value, and the undefined type has only one value undefined . Null: means that the variable has no value or is empty. Except for the above type, the o

number. That is to say, a constant or infinity should be added to an infinity, and 0x7fffff + 1 will overflow. Obviously, this does not meet this basic requirement. So we found 0x3f3f3f3f (which is the first big God to use this number). Its value is 1061109567, that is, 10 ^ 9, which is an order of magnitude higher than 0x7fffffff, it adds a constant still in the range of 32int... more importantly, an infi

back the ancient Ancient ancient Greece 2000 years ago, the age of mathematics. With the advanced prosperity of mathematics in ancient Greece, the creed of the Pythagoras school "Everything is a number" fully expresses the admiration of people. However, at that time, the number only refers to a general integer. People have always avoided the irrational number or the concept of an infinite number.
