Find Base-10 Exponential of Given Number in Golang

Go language provides inbuilt support for basic constants and mathematical functions to perform operations on the numbers with the help of the math package. You can find the base-10 exponential(10**a) of the specified number with the help of the pow10() function provided by the math package. So, you need to add a math package in your program with the help of the import keyword to access the Pow10() function.

Syntax:

func Pow10(a int) float64

• If the value of a<-323, then this function will return 0.
• If the value of a>308, then this function will return +Inf.

Example 1:

// Golang program to illustrate how to find
// base-10 exponential of the given numbers

package main

import (
    "fmt"
    "math"
)

// Main function
func main() {

    // Finding the base-10 exponential
    // of the given numbers
    // Using Pow10() function
    res_1 := math.Pow10(3)
    res_2 := math.Pow10(-2)
    res_3 := math.Pow10(310)
    res_4 := math.Pow10(-300)

    // Displaying the result
    fmt.Printf("Result 1: %.1f", res_1)
    fmt.Printf("\nResult 2: %.1f", res_2)
    fmt.Printf("\nResult 3: %.1f", res_3)
    fmt.Printf("\nResult 4: %.1f", res_4)

}

Output:

Result 1: 1000.0
Result 2: 0.0
Result 3: +Inf
Result 4: 0.0

Example 2:

// Golang program to illustrate how to find
// base-10 exponential of the given numbers

package main

import (
    "fmt"
    "math"
)

// Main function
func main() {

    // Finding the base-10 exponential
    // of the given numbers
    // Using Pow10() function
    nvalue_1 := math.Pow10(2)
    nvalue_2 := math.Pow10(3)

    // Sum of the given exponentials
    res := nvalue_1 + nvalue_2
    fmt.Printf("%.2f + %.2f = %.2f",
            nvalue_1, nvalue_2, res)

}

Output:

100.00 + 1000.00 = 1100.00
