## math.Pow10()

The Pow10() function is an inbuilt function of the math package which is used to get the 10**n, the base-10 exponential of n (we can say, 10 to the power n).

It accepts a parameter (n) and returns the 10**n, the base-10 exponential of n.

Syntax:

```func Pow10(n int) float64
```

Parameter(s):

• n : The value to be used to find 10**n (10 to the power n).

Return Value:

The return type of Pow10() function is a float64, it returns the 10**n, the base-10 exponential of n.

Special cases:

• Pow10(n) = 0 for n < -323
If the parameter is less then -323, the function returns 0.
• Pow10(n) = +Inf for n > 308
If the parameter is greater than 308, the function returns +Inf.

Example 1:

```// Golang program to demonstrate the
// example of math.Pow10() Function

package main

import (
"fmt"
"math"
)

func main() {
fmt.Println(math.Pow10(2))
fmt.Println(math.Pow10(3))
fmt.Println(math.Pow10(-10))
fmt.Println(math.Pow10(10))
fmt.Println(math.Pow10(149))

fmt.Println(math.Pow10(0))
fmt.Println(math.Pow10(1))
fmt.Println(math.Pow10(-324))
fmt.Println(math.Pow10(309))
}
```

Output:

```100
1000
1e-10
1e+10
1e+149
1
10
0
+Inf
```

Example 2:

```// Golang program to demonstrate the
// example of math.Pow10() Function

package main

import (
"fmt"
"math"
)

func main() {
var n int
var result float64

n = 2
result = math.Pow10(n)
fmt.Println(10, "to the power of", n, "is", result)

n = 3
result = math.Pow10(n)
fmt.Println(10, "to the power of", n, "is", result)

n = 15
result = math.Pow10(n)
fmt.Println(10, "to the power of", n, "is", result)

n = 0
result = math.Pow10(n)
fmt.Println(10, "to the power of", n, "is", result)

n = 309
result = math.Pow10(n)
fmt.Println(10, "to the power of", n, "is", result)
}
```

Output:

```10 to the power of 2 is 100
10 to the power of 3 is 1000
10 to the power of 15 is 1e+15
10 to the power of 0 is 1
10 to the power of 309 is +Inf
```
