First, the basic data type:byte: Smallest data type in Java, 8 bits in memory (bit), 1 bytes, value range -128~127, default value 0short: Shorter integer, 16 bits in memory, 2 bytes, range -32768~32717, default value 0int: integral type, used to

Basic data types and packaging types of JavaScript systems, javascript Data Types Preface Javascript data types can be divided into two types: original type and reference type. The original type is also known as the basic type or simple type.

Integers and floating-point numbersPython supports four blending of integers and floating-point numbers directly, and the arithmetic rules are exactly the same as the arithmetic rules in mathematics.Basic operations:1 + 2 + 3 # ==> * 5-6 # ==> 14

Data types are used when declaring variables, and some data types, such as integers and strings, are used earlier. All data types in Python are classes, and each variable is an "instance" of the class. There is no concept of a basic data type, so
