How Go language implements four arithmetic operations

In the Go language, the four arithmetic operations are implemented through basic arithmetic operators. Four commonly used arithmetic operations: 1. Addition ( ): used to add two numbers; 2. Subtraction (-): used to subtract the second number from the first number; 3. Multiplication (*) : Used to multiply two numbers; 4. Division (/): Used to divide the first number by the second number.

In the Go language, the four arithmetic operations are implemented through basic arithmetic operators. The following are the four commonly used arithmetic operations:

1. Addition ( ): used to add two numbers.

sum := a + b

2. Subtraction (-): Used to subtract the second number from the first number.

difference := a - b

3. Multiplication (*): Used to multiply two numbers.

product := a * b

4. Division (/): Used to divide the first number by the second number.

quotient := a / b

The four arithmetic operations in Go language follow basic mathematical rules, and the type requirements are relatively strict. For example, if a and b are both integers, the result of the division operation will be an integer. If you want a floating point result, you can convert one of the numbers to a floating point type.

result := float64(a) / float64(b) // 将a和b转换为浮点数进行除法运算

In practical applications, variables are usually used to store operation results instead of directly using the value of the operation expression for subsequent calculations or other operations.
