C# has a built-in `Math` class that provides useful mathematical functions and operations. The `Math` class has the **`Pow()`** function, which is used to compute the *power* of a specified number.

public static double Pow (double value, double power);

- **`value`**: `value` is a double-precision floating-point number of type `Double` and represents the number to be raised with power. Its range is all double numbers.
- **`power`**: `power` is a double-precision floating-point number of type `Double` and represents the power value. Its range is all double numbers.



- **`Double`**: `Pow()` returns a number, `value`, raised to the power, `power`, and its type is `Double`. 

- **`NaN`**: `Pow()` returns `NaN` if:
  - `value` or `power` is `NaN`.
  - `value` = -1; `power` = `NegativeInfinity` or `PositiveInfinity`.
  - `value` < 0 but not `NegativeInfinity`; `power` is not an integer, `NegativeInfinity`, or `PositiveInfinity`.

- **`PositiveInfinity`**: `Pow()` returns `PositiveInfinity` if:
   - `value` = `NegativeInfinity`; `power` is positive but not an odd integer.
   - -1 < `value` < 1; `power` = `NegativeInfinity`.
   - `value` < -1 or `value` > 1; `power` = `PositiveInfinity`
   - `value` = 0; `power` < 0.
   - `value` = `PositiveInfinity`; `power` > 0
- **`NegativeInfinity`**: `Pow()` returns `NegativeInfinity` if:
   - `value` = `NegativeInfinity`; `power` is a positive odd integer.


using System;
class Educative
{
    static void Main()
    {
        Double result = Math.Pow(-0.16, 2);
        System.Console.WriteLine("Pow(-0.16,2) = "+ result);

        Double result1 = Math.Pow(0, 0);
        System.Console.WriteLine("Pow(0,0) = "+ result1);

        Double result2 = Math.Pow(2,4);
        System.Console.WriteLine("Pow(2,4) = "+ result2);

        Double result3 = Math.Pow(-2,-4);
        System.Console.WriteLine("Pow(-2,-4) = "+ result3);
    }
}

What is Math.Pow() in C#?

Computes a number raised to a power using double-precision. It handles special cases returning NaN, PositiveInfinity, or NegativeInfinity.
