Go 程序查找数字的平方根

这个 Go 程序使用用户给定的值来查找数字的平方根，它调用了内置的 math.Sqrt 函数。

package main

import (
    "fmt"
    "math"
)

func main() {

    var sqrtnum, sqrtOut float64

    fmt.Print("\nEnter the Number to find Square Root = ")
    fmt.Scanln(&sqrtnum)

    sqrtOut = math.Sqrt(sqrtnum)

    fmt.Println("\nThe Square of a Given Number  = ", sqrtOut)
}

SureshMac:GoExamples suresh$ go run squareroot1.go

Enter the Number to find Square Root = 64

The Square of a Given Number  =  8
SureshMac:GoExamples suresh$ go run squareroot1.go

Enter the Number to find Square Root = 82

The Square of a Given Number  =  9.055385138137417

Golang 程序查找数字的平方根

这个 golang 程序 使用 math.Pow 函数来计算给定数字的平方根。

package main

import (
    "fmt"
    "math"
)

func main() {

    var sqrtnum, sqrtOut float64

    fmt.Print("\nEnter the Number to find Square Root = ")
    fmt.Scanln(&sqrtnum)

    sqrtOut = math.Pow(sqrtnum, 0.5)

    fmt.Println("\nThe Square of a Given Number  = ", sqrtOut)
}
