Submitted by IncludeHelp, on September 01, 2021
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
Parameters
- 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
