Ruby Integer Data Type

Ruby has two types of data: integer and string. Ruby is fully oo. Programming LanguageDifferent from C ++, its integers and strings are also class types. There are two types of integer. When the integer value ranges from-2 ^ 30 to 2 ^ 30-1 (or-2 ^ 62 to 2 ^ 62-1, related to the machine code length, the fixnum class type is used. If it is not in the preceding range, the bignum class type is used. The bignum class type can represent the maximum value that can be expressed in the remaining memory space, it is composed of a series of short integers. Frequently Used members include: ID, (an uncertain number) class, (Class Name) times, (repeated times) upto (m), (until m value) downto (m), (until the m value) Step (M, S) (to S for the order until m ). When a piece of data is relatively long, you can use "_" to connect to the data, such as 8_1 equal to 81? \ C-X is used to obtain the value after X & 0x9f? \ M-X is used to obtain the value after X | 0x80? X indicates the ASCII code value of X.
