int long

int is the ellipsis of short int, which accounts for 2 bytes of memory, representing the range: -32768~32767.Long is an ellipsis of long int, which accounts for 4 bytes of memory, representing the range: -2147483648~2147483647.Long Long is twice

First, we want to understand the meaning of "bit", "byte", "word" (word), these three.bit is the smallest unit of storage and can only be placed in a machine language of 0 or 1.Byte (byte), 8 bits (bit) is a byte, so 1 bytes = 8 bits, 4 bytes is 32

Lucky to taste the mango today, found that there are many types of self-growth ID, but no long/int.One idea:1. Self-built a collection (table, assuming named: Identityentity, where Fields: _id, Key, Value, _id you know, key:collection name, need

Database fields such as amount, weight, and score are recommended for use with an int or bigint type.Usually our database design in the amount, weight and other fields related to the decimal place will be used float or decimal,mysql can also use

Python supports four different numeric types, including int (integer) long (Long integer) float (floating point actuals) complex (complex number), Numeric data types store values. They are immutable data types, which means changing the value of the
