## math.Log10E Constant

The Log10E constant is an inbuilt constant of the math package which is used to get the base-10 logarithm of the mathematical constant e, approximately equal to 1. 0.43429448. The math.Log10E constant is equivalent to 1/math.Ln10.

Syntax:

```float64 math.Log10E
```

Parameter(s):

• None

Return Value:

The return type of math.Log10E constant is float64, it returns the base-10 logarithm of mathematical constant e.

Example 1:

```// Golang program to demonstrate the
// example of math.Log10E Constant

package main

import (
"fmt"
"math"
)

func main() {
fmt.Printf("Type of math.Log10E is %T\n", math.Log10E)
fmt.Println("Value of math.Log10E:", math.Log10E)
}
```

Output:

```Type of math.Log10E is float64
Value of math.Log10E: 0.4342944819032518
```

Explanation:

In the above program, we imported the math package to use the math.Log10E constant, then printed the type and value of the math.Log10E constant.

Example 2:

```// Golang program to demonstrate the
// example of math.Log10E Constant

package main

import (
"fmt"
"math"
)

// creating function to
// return the value of Log10E.
func getLog10E() float64 {
return math.Log10E
}

func main() {
fmt.Println("Value of math.Log10E:", getLog10E())
}
```

Output:

```Value of math.Log10E: 0.4342944819032518
```
