Golang Math Package Guide

In the Go language, the math package provides basic mathematical functions and constants. This package can be used for mathematical calculations and operations such as calculating square roots, finding absolute values, and performing rounding operations. The functions included in the math package are Sin, Cos, Tan, Sqrt, and the constants included are Pi and E. To use the functions and constants in the math package, simply import the math package in the code and then directly call the corresponding functions and constants. For example:

import "math"

func main() {
    x := 16.0
    y := math.Sqrt(x)
    fmt.Println(y) // 输出：4.0
}

The code above demonstrates how to use the Sqrt function from the math package to calculate the square root of a number. By importing the math package, we can easily perform mathematical operations.
