Find Base-10 Exponential of Given Number in Golang
  • Last Updated : 13 Apr, 2020

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
