The **math.Pow()** in **Golang** is a built-in function that returns the result of raising a given base to a given exponent. It accepts two arguments of type **float64**: the **base** and the **exponent**. It returns a

value is the result of raising the base to the exponent power.**float64**

**Syntax**

`func Pow(x, y float64) float64`

**Parameters**

It takes two arguments of ** float64 **data type, which has IEEE-754 64-bit floating-point numbers.

**Return value**

The **Pow()** function returns **x**y,** the **base-x** exponential of **y**.

**Special cases**

```
Pow(x, ±0) = 1 for any x
Pow(1, y) = 1 for any y
Pow(x, 1) = x for any x
Pow(NaN, y) = NaN
Pow(x, NaN) = NaN
Pow(±0, y) = ±Inf for y an odd integer < 0
Pow(±0, -Inf) = +Inf
Pow(±0, +Inf) = +0
Pow(±0, y) = +Inf for finite y < 0 and not an odd integer
Pow(±0, y) = ±0 for y an odd integer > 0
Pow(±0, y) = +0 for finite y > 0 and not an odd integer
Pow(-1, ±Inf) = 1
Pow(x, +Inf) = +Inf for |x| > 1
Pow(x, -Inf) = +0 for |x| > 1
Pow(x, +Inf) = +0 for |x| < 1
Pow(x, -Inf) = +Inf for |x| < 1
Pow(+Inf, y) = +Inf for y > 0
Pow(+Inf, y) = +0 for y < 0
Pow(-Inf, y) = Pow(-0, -y)
Pow(x, y) = NaN for finite x < 0 and finite non-integer y
```

**Example 1**

Use the **math.Pow()** function to calculate **x** to the power **y **in Go.

```
package main
import (
"fmt"
"math"
)
func main() {
var x float64
x = math.Pow(2, 3)
fmt.Println(x)
}
```

**Output**

**8**

**Example 2**

```
package main
import (
"fmt"
"math"
)
func main() {
base := 3.0
exponent := 4.0
result := math.Pow(base, exponent)
fmt.Printf("%v ^ %v = %v \n", base, exponent, result)
}
```

**Output**

`3 ^ 4 = 81`

Additionally, be aware of the limitations of floating-point arithmetic, especially when dealing with very large or very small numbers.

**Error Handling**

The **math.Pow()** function will throw an error if the two input parameters, x or y, are not numbers.

The compiler will issue an error if the function is called without an argument (the input value, x or y).

**FAQ**

**What is the math.Pow() function in Go?**

**Golang math.Pow()** function takes two arguments, the base and the exponent, and returns the result of raising the base to the exponent power.

**What are the arguments and return value of the math.Pow() function?**

The math.Pow() function takes two arguments, both of type float64, and returns a float64 value, which results from raising the base to the exponent power.

**How is the math.Pow() function used in programming?**

The** math.Pow()** function is used in programming for computing exponentials and powers.

**Conclusion**

**Golang math.Pow()** is a built-in function that takes two float64 arguments, the base and exponent, and returns the result of raising the base to the exponent power.
