math.Log10()

The Log10() function is an inbuilt function of the math package which is used to get the decimal logarithm (base-10 logarithm) of the given number.

It accepts a parameter (x) and returns the decimal logarithm of x.

Syntax:

func Log10(x float64) float64

Parameter(s):

• x : The value whose decimal logarithm is to be found.

Return Value:

The return type of Log10() function is a float64, it returns the decimal logarithm of the given value.

Special cases:

• Log10(+Inf) = +Inf
  If the parameter is positive infinity (+Inf), the function returns the same (+Inf).
• Log10(0) = -Inf
  If the parameter is 0, the function returns the -Inf.
• Log10(x < 0) = NaN
  If the parameter is less than 0, the function returns NaN.
• Log10(NaN) = NaN
  If the parameter is NaN, the function returns NaN.

Example 1:

// Golang program to demonstrate the
// example of math.Log10() Function

package main

import (
	"fmt"
	"math"
)

func main() {
	fmt.Println(math.Log10(1))
	fmt.Println(math.Log10(2))
	fmt.Println(math.Log10(10))
	fmt.Println(math.Log10(10.23))

	fmt.Println(math.Log10(0))
	fmt.Println(math.Log10(-1))
	fmt.Println(math.Log10(math.NaN()))
	fmt.Println(math.Log10(math.Inf(1)))
}

Output:

0
0.3010299956639812
1
1.0098756337121602
-Inf
NaN
NaN
+Inf

Example 2:

// Golang program to demonstrate the
// example of math.Log10() Function

package main

import (
	"fmt"
	"math"
)

func main() {
	var x float64
	var Log10X float64

	x = 1
	Log10X = math.Log10(x)
	fmt.Println("Log10(", x, ") =", Log10X)

	x = 2
	Log10X = math.Log10(x)
	fmt.Println("Log10(", x, ") =", Log10X)

	x = 10
	Log10X = math.Log10(x)
	fmt.Println("Log10(", x, ") =", Log10X)

	x = 10.58
	Log10X = math.Log10(x)
	fmt.Println("Log10(", x, ") =", Log10X)

	x = math.Inf(1)
	Log10X = math.Log10(x)
	fmt.Println("Log10(", x, ") =", Log10X)

	x = math.NaN()
	Log10X = math.Log10(x)
	fmt.Println("Log10(", x, ") =", Log10X)
}

Output:

Log10( 1 ) = 0
Log10( 2 ) = 0.3010299956639812
Log10( 10 ) = 1
Log10( 10.58 ) = 1.024485667699167
Log10( +Inf ) = +Inf
Log10( NaN ) = NaN
